----------- Carve booleans library integration ==================================

Merging Carve library integration project into the trunk.

This commit switches Boolean modifier to another library which handles mesh boolean operations in much stable and faster way, resolving old well-known limitations of intern boolop library.

Carve is integrating as alternative interface for boolop library and which makes it totally transparent for blender sources to switch between old-fashioned boolop and new Carve backends.

Detailed changes in this commit:

- Integrated needed subset of Carve library sources into extern/ Added script for re-bundling it (currently works only if repo was cloned by git-svn). - Added BOP_CarveInterface for boolop library which can be used by Boolean modifier. - Carve backend is enabled by default, can be disabled by WITH_BF_CARVE SCons option and WITH_CARVE CMake option. - If Boost library is found in build environment it'll be used for unordered collections. If Boost isn't found, it'll fallback to TR1 implementation for GCC compilers. Boost is obligatory if MSVC is used.

Tested on Linux 64bit and Windows 7 64bit.

NOTE: behavior of flat objects was changed. E.g. Plane-Sphere now gives plane with circle hole, not plane with semisphere. Don't think it's really issue because it's not actually defined behavior in such situations and both of ways might be useful. Since it's only known "regression" think it's OK to deal with it.
