Migration to Visual C++ 2010, availability of x64 builds

Yeah i’ve encountered an issue where the buildbot builds crash if i attach rigid bodies to the bullet world this also happens if i compile panda myself but depending on what optimize level i use i get different errors.pstats doesn’t work at optimize 4 and bullet crashes with no optimizing im am rebuilding with something in between right now but i thought you should know of these.

Also note i don’t know what optimize does lol.
