Note: this commit includes new functionality to save and restore scripts configure options. This is ongoing work, scripts still have to be updated to use this feature and more tests are needed, though many have been performed. The new Scripts Config Editor script is the main part of this. If anyone wants to check it, only the AC3D importer and exporter have already been updated to use it: simply open them (you can then cancel with ESC) to have the data created, then try the config editor.

Scripts:
- Thanks Jean-Michel Soler (jms) for updated versions of dispaint, fixfromarmature and unweld (also renamed to remove version part).
- Thanks Bart for the upgraded VRML exporter (great doc webpage!).  It is available as VRML 97 and the original VRML 2 is for now still there, to help users testing the new version.  For the next release the old one should be removed, of course.
- New script: Scripts Config Editor (Scripts win -> Scripts -> System).  Scripts with config options (simple data that is to be set according to user needs or preferences) can use this facility instead of providing a gui and writing config files to disk themselves.
- Added new menu: System, available in the Scripts win.
- Updated sys_info.py, help_browse.py and the AC3D importer and exporter.
- Removed use of the Scrollbar and added arrow keys and mouse wheel support instead in Daniel Dunbar's old doc_browser.py. The scrollbar events handling doesn't exist, Ton suggested removing the scrollbar from the API months ago.  For now its ref doc is gone and no bundled script uses it, until we get time to implement it properly.
- Added module BPyRegistry.py with functions to handle reading / writing config files automatically to the scripts/bpydata/config dir.
- Removing dir release/bpydata and its contents (moved earlier to release/scripts/bpydata/)
- Bug #2379: made small changes to bevel_center's ui to fix a problem reported by Alexander Ewering (intrr):
http://projects.blender.org/tracker/?func=detail&atid=125&aid=2379&group_id=9

BPython:
- Thanks Campbell Barton for new functionality: Blender.Get() now can also return all the paths from the user prefs -> file paths win and there is a new function: Blender.sys.expandpath() to transform Blender paths (those starting with '//' and ending with '#') to absolute paths.
- Added function Blender.ShowHelp(), to open the Scripts Help Browser with a given help page -- just a time saver for scripts.
- Improved function Blender.Run() to also work with gui and file select scripts.
- Found a (new?) crash related to NMesh.PutRaw when creating a new object while in edit mode.  Leaving / entering edit mode fixes the problem, so a check for obj created, edit mode and leaving / re-entering it were added to the code for now (gdb didn't help much, no backtrace)
- doc updates, including splitting intro page in two, with bpython related stuff (registering / documenting / configuring scripts and command line mode (thanks Chris Want for "use system variables to pass parameters to scripts" idea).
- Registry: functions have been updated to support writing to / reading from disk, for the config editor -- only simple config data supported, for large amounts coders should write to a file themselves.  This is done with a new parameter: Registry.GetKey(keyname, True) will also search for the key on the config dir, if not already loaded; equiv. for Registry.SetKey(keyname, dict, True).  Data is only written to / read from disk when needed and only scripts already used (assuming they support this functionality) will have config data saved.

+Name: 'Scripts Config Editor'
+Blender: 236
+Group: 'System'
+Tooltip: 'View and edit available scripts configuration data'
+"""
+
+__author__ = "Willian P. Germano"
+__version__ = "0.1 2005/04/14"
+__email__ = ('scripts', 'Author, wgermano:ig*com*br')
+__url__ = ('blender', 'elysiun')
+
+__bpydoc__ ="""\
+This script can be used to view and edit configuration data stored
+by other scripts.
+
+Technical: this data is saved as dictionary keys with the
+Blender.Registry module functions.  It is persistent while Blender is
+running and, if the script's author chose to, is also saved to a file
+in the scripts config data dir.
+
+Usage:
+
+- Start Screen:
+
+To access any available key, select it from (one of) the menu(s).
+
+Hotkeys:<br>
+   ESC or Q: [Q]uit<br>
+   H: [H]elp
+
+- Keys Config Screen:
+
+This screen exposes the configuration data for the chosen script key.  If the
+buttons don't fit completely on the screen, you can scroll up or down with
+arrow keys or a mouse wheel.  Leave the mouse pointer over any button to get
+a tooltip about that option.
+
+Any change can be reverted -- unless you have already applied it.
+
+If the key is already stored in a config file, there will be a toggle button
+(called 'file') that controls whether the changes will be written back to
+the file or not.  If you just want to change the configuration for the current
+session, simply unset that button.  Note, though, that data from files has
+precedence over those keys already loaded in Blender, so if you re-run this
+config editor, unsaved changes will not be seen.
+
+Hotkeys:<br>
+   ESC: back to Start Screen<br>
+   Q: [Q]uit<br>
+   U: [U]ndo changes<br>
+   ENTER: apply changes (can't be reverted, then)<br>
+   UP, DOWN Arrows and mouse wheel: scroll text up / down
+
+Notes:
+
+a) Available keys are determined by which scripts you use.  If the key you
+expect isn't available (or maybe there are none or too few keys), either the
+related script doesn't need or still doesn't support this feature or the key
+has not been stored yet, in which case you just need to run that script once
+to make its config data available.
+
+b) There are two places where config data files can be saved: the
+bpydata/config/ dir (1) inside the default scripts dir or (2) inside the user
+defined Python scripts dir
+(User Preferences window -> File Paths tab -> Python path).  If available,
+(2) is the default and also the recommended option, because then fresh Blender
+installations won't delete your config data.  To use this option, simply set a
+dir for Python scripts at the User Preferences window and make sure this dir
+has the subdirs bpydata/ and bpydata/config/ inside it.
+
+c) The key called "General" in the "Other" menu has general config options.
+All scripts where that data is relevant are recommended to access it and set
+behaviors accordingly.
