1. UI review -> disabling options when not available .. giving hints why ( even tried to give useful tooltips )

1.1 give some more user control to the solving process (mins,maxs).. optional feedback on the console

2. replacing ugly object level 'sumohandle' with SB (private runtime) level/pointer 'scratch' which holds runtime data like cached collider data and more .. and it's thread save this way :)

3.related no 2. write a 'private' history of collision objects to ease the 'fast' collider tunneling syndrome'

4. some <clean> optimizations, 3-BSP for self collision, general AABB checking before ever going to collision details

5. some <dirty> (in the sense of inaccurate physics that do not create much negative results to the simulation) little tricks to make things faster

.. ..fuzzy collision situation bypass .. forward collision resolution

Added a less 'strict' solver step size control. Cuts down needed loops to a 1/5 in 'regular' collision situations. So why be a maths smartass when we want to do a skirt in a breeze :) Is on by default, old mode can be turned on with the 'O' button beside the RK-limit.

Some minor fixes to the UI

nice little 'debug' feature
SHIFT_ESC breaks baking without throwing away the baked keys
so you can check the solution calculated so far
baked sb replay checks for NULL pointers in keys -> motion will stop there
even saving and loading to file works here,
but i would not expect it to do so
humm .. may be i'll add a dirty flag for that

nicer kinematics in self collision -> blending to complete inelastic impact
now does something close to real physics

first steps towards aerodynamics
anisotropic friction
springs 'see' their movement in media
--> see surrrounding media does not move and/or reacts on wind
(*for now needs to have a pseudo collider araound -> that is: add a cube in the same layer
and make it a deflector *)

softbody update -> self collision search takes 1/3 of the time here
this one should work nice --> (you should not link to internal info!)

humm .. well .. as some of you might know, i tried to write some docs
--> http://mosebjorn.altervista.org/newsb/ response looks like 3 bins :
1. Ahh! that's what i've been waiting for.
2. Nice, but i don't need it.
3. Yelling for
3.1 'get it faster' (yup .. we're doing our very best)
3.2 'make it easier to use' ....
well ..
some users do know what they are doing proof -->
see --> http://blenderartists.org/forum/showthread.php?t=88065
.
3.3
'add another UI control for *schlotziness*'
sigh .. see 3.2
