2.5

View3D has been split now in a local part (RegionView3D) and a
per-area part (old View3D). Currently local is:

- view transform
- camera zoom/offset
- gpencil (todo)
- custom clipping planes

Rest is in Area still, like active camera, draw type, layers,
localview, custom centers, around-settings, transform widget,
gridlines, and so on (mostly stuff as available in header).

To see it work; also added new feature for region split, 
press SHIFT+ALT+CTRL+S for four-split. 
The idea is to make a preset 4-split, configured to stick
to top/right/front views for three views.
Another cool idea to explore is to then box-clip all drawing
based on these 3 views.

Note about the code:
- currently view3d still stores some depricated settings, to
  convert from older files. Not all settings are copied over
  though, like custom clip planes or the 'lock view to object'.
- since some view3d ops are now on area level, the operators
  for it should keep track of that.

Bugfix in transform: quat initialize in operator-invoke missed
one zero.

Als brought back GE to compile for missing Ipos and channels.
