MSVC Builds: Improve Build Speed and Debugging
MSVC Builds: Improve Build Speed and Debugging

Use Multiprocessor compilation which can cut down build times by quite a
bit and use the /d2Zi+ flag to have better debugging info being logged to
the .pdb for release builds.

These are only applicable for Visual Studio 2010/2012 and later.
