This isn't how Windows stores the COR version, why are we doing it this way?

Windows doesn't store the version anywhere, it's hardcoded in each of the 
installed runtimes and the mscoree.dll returns one of them - for 
GetCORVersion it returns the highest available, for other functions 
depends on what the executable requires.

But remember, we are just _emulating_ windows and sometimes we need to 
pretend we have a different version.
