Title: Forgot that the main VC project needed the file as well.

Well, the previous PR did fix the VC 2008 project, as well as make color.c and color.h show up in the project in Visual Studio, but I failed to add it to the main project file for VC 2010, so it wasn't actually being compiled. This fixes that.
