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
enable MPR by default, needs more testing on various OpenCL configurations (OS, drive, GPU etc)
disable MPR until some issues are fixed (on an NVIDIA GPU, sat axis are not properly computed, resulting in instability)
Move Bullet 2.x demos in a single demo 'AllBullet2Demos', for now only BasicDemo and FeatherstoneDemo is implemented.
fix Mac OSX build
fixes to improve demos a bit
add missing file
rename files, fix Linux build
multidof4 patch
dirty changes - stabilization hacks
first experiments with RK4
made the multiDof-singleDof disctinction a bit cleaner
a bit of rk4 clean-up
RK4 for floating systems too
minor naming chamge
dirty commit: experimenting with the 6DoF grabbing/p2p constraint
tighter packing in btMultiBodySolverConstraint
dirty commit: starting to unify btMultiBoydConstraint::fillMultiBodyConstraint..(..)
fixed a jacobian sizing bug (m_jacSizeBoth)
unified btMultiBodyConstrained::fillMultiBodyConstraint..(...) mtds + cleaned some of the earlier dirty changes (6DoF grabbing constraint stuff mainly)
