implement GPU breakable constraints
...
add GPU fixed constraint
fix performance issue with concave meshes (didn't clear the number of concave-convex pairs, so it increased every frame)

remove some debug printf's from kernel (stringify doesn't handle it properly)

add some clFinish for better profile timings
...
improved parallel batching, don't try to write for static objects,
this fixed a bug, when the hash of a static object was identical with hash of dynamic objects, causing it to be assigned a bogus 100+i batching number
The parallel batching is still not enabled, because we need to measure the batching size (todo)

made the simulation deterministic
...
disable 'simdwidth' optimization for determinism (need to double-check)
made the spatial batching 3D

added GPU joint solver for non-contact constraints. Only point 2 point version for now, will add some other constraints soon (changes are very local)

joint (non-contact constraint) solver iterations is now working on GPU, but overall slower because of data copy.
...
Will move joint setup to GPU, and then some benefit should be visible.
Don't use 64 alignment, it causes data structures size mismatch between cpu and gpu

experiment with first-level batching using object index instead of spatial hash in uniform grid (to avoid tuning average object size for uniform grid)

fix bug in assignment of contact constraints to solver grid (always use dynamic body to determine constraint assignment, otherwise write conflicts can occur)
...
implement CPU version of narrowphase convex collision, for comparison/debug purposes
start towards cpu/gpu sync, for adding/removing bodies (work in progress)

add bitonic sort, as comparison.
...
fix stringify.bat for Windows (need to fix Mac/Linux version too)
