Add visual studio 2013 files

Thanks for your contribution!

I spent a few hours to add visual studio 2013 files, fix c2039 errer which caused by missing "#include <algorithm>" in visual studio 2013, and tested all projects in visual studio 2013 (12.0.30501.00 Update 2), they all built successfully!

The successfully built targets contain: ad, git_id, Recast, Detour, MoveMapGen, vmap_assembler, libmpq, vmapExtractor, bzip2, framework, g3dlite, game, genrevision, script, shared, tbb, tbbmalloc, zlib, realmd, mangosd;

Thank you!
