[8735] New memory allocator for MaNGOS, based on Intel Threading Building Blocks library. Performance gains depend greatly on OS you use!

Browse source 
You should add two libraries into your server binaries:
tbb.so/tbbmalloc.so on *nix and tbb(_debug).dll/tbbmalloc(_debug).dll on Windows!!!

Define USE_STANDARD_MALLOC while compiling 'framework' project to use OS' default memory allocator!
