softbody review

1. UI review -> disabeling options when not available .. giving hints why ( even tried to give usefull 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 do some inacurate physics noone ever will see ) little tricks to make things faster .. ..fuzzy collision situation bypass .. forward collision resolution
