more fixes towards working convex-convex, in case of (too) many edge-edge cases:
...
1) sample directions over a unit sphere and
2) add a contact, using mpr
add missing bullet.pc.cmake file (for old Bullet 2.x)

Ported Minkowski Portal Refinement mpr.c from libccd to OpenCL, for bettwe edge-edge performance (and additional contact point for degenerate/high detailed convex shapes)
...
Removed b3RigidBodyCL, replace by b3RigidBodyData and b3RigidBodyData_t shared between C++ host and OpenCL,
Same for b3InertiaCL -> b3InertiaData

support compound versus compound collision shape acceleration on GPU, using aabb tree versus aabb tree.
...
Remove constructor from b3Vector3, to make it a POD type, so it can go into a union (and more compatible with OpenCL float4)
Use b3MakeVector3 instead of constructor
Share some code between C++ and GPU in a shared file: see b3TransformAabb2 in src/Bullet3Collision/BroadPhaseCollision/shared/b3Aabb.h
Improve PairBench a bit, show timings and #overlapping pairs.
Increase shadowmap default size to 8192x8192 (hope the GPU supports it)

added (and stripped) a simple C/C++ preprocessor (written in Lua), so the stringifier can handle the #include directive,
...
and embed the included files directly in the stringified files.
We need this, because we start sharing struct definitions and code between C/C++ and OpenCL (and potentially other languages)
preprocessor is from http://github.com/willsteel/lcpp

use Syoyo Fujita's Wavefront obj loader. made some performance improvements in debug mode for Visual Studio
...
use Maya style controls under Windows (need to fix Linux/OSX) use ALT+mouse to rotate, and mouse pick to pick objects

faster scene construction when not using instancing (avoid copy individual vertices/shapes to GPU, but do it afterwards in a batch), copy GPU data in 'writeAllBodiesToGpu' method
...
add option --no_instanced_collision_shapes, this only applies to the 2 benchmark screnes at the moment
always use the user specified b3Config file, so the settings can be set at runtime, not just at compile time
adjust default constants in b3Config (needs more tweaking, ideally at run-time)
