Whole lot of changes.... here a shortlist:

- removed editors/area and put this all in screen
- added first python calls (note, a new c file for scriptlinks)
- added view3d editor callbacks (no drawing yet)
- added files in editors/interface

(Cmake and Scons has to be fixed, help welcome!)

- now areas/headers are being converted on file read
- note: previously saved 2.50 files will crash!!! (.B.blend)
- area regions are being drawn, first handler for cursor added (on edge)
- window duplicate and scale works correct for screen subdiv

Todos for me:

- need to fix things in syntax (function names) a bit still
- more operators for screen
- define how Context will work... still unresolved when it gets set
- docs!

Reviews of code structure is welcome!
There are also more todos now for others, but it can wait a couple of days
