Fix various Visual Studio project issues
1) never assume CUDA and CG to be system-wide includes, but explicitly set it up in the project
2) add tinyxml files
3) use regular Glut and add glut32.lib, glut32.dll and GL/glut.h
4) add missing CUDA utility files (they are obsolete in the CUDA sdk, and only for 'demos', so explicitly add them)
5) don't use .. as target path but simply Debug or Release folder
