Fix in btQuickprof that caused crash in ConcaveConvexcastDemo.cpp

Thanks to Roman Ponomarev for the report
Make btVector3::rotate const
Thanks to lepoussin, see Issue 428
CMakeLists.txt improvement: don't copy resources when INTERNAL_CREATE_DISTRIBUTABLE_MSVC_PROJECTFILES is set
CMakeLists.txt improvement: INSTALL_EXTRA_LIBS for ConvexDecomposition and GIMPACTUtils
Thanks to andrebra, see Issue 425
