Blender Git Loki

Integration stage of Softbody project

User level notes are in Wiki here;
http://wiki.blender.org/bin/view.pl/Blenderdev/Softbodies
And will be added in blender3d.org CMS later.

Tech level notes are still pending, but here's the most relevant ones;

- made ob->soft struct SoftBody to hold all settings, and read/save in
files
- added (temporal!) conversion for the old settings. So: read old files
with softbody experiments now, and save over!
- cleaned API calls for softbody, which are only 5 of them now:
sbNew()
sbFree()
sbObjectStep() (animation steps)
sbObjectToSoftbody() (full re-initialize data)
sbObjectReset() (only reset motion)
- API calls accepts time in frames now, within softbody.c it converts

Further, internally code was cleaned some (missing tabs etc). Also tried
to keep a well defined structure with hints how to add support for more
objects. Can write notes about that...
