BPython - first step for better integration of Python in Blender:

- add a new space: Space Script
- add a new dna struct: Script
- add these two properly everywhere they are meant to

It's not a tiny commit, but most of it is ground work for what is still to be done.
Right now the benefits should be: freeing the Text Editor to be used in a window even while a script w/ gui in "on" and letting more than one currently running script w/ gui be accessible from each window

Some files are added, so some build systems (not autotools) will need updates
