[svn-r15815] Purpose: Add new source code and tests to Windows

Description:
Many new source files were added from the freespace branch.  This checkin adds the code to Windows as well.

Note: Some tests are still failing on Windows, but this checkin brings us closer to fixing them.  In particular, freespace test fails on compile (Quincey is working on it), and the DLL links test fails at runtime (I'll look into it)

Tested:
VS2005 on WinXP
