mscoree: Invoke installed win32 mono runtime or exec mono native for .NET executables

I tried your patch with Win32 Mono-1.1.17.2 installed but the MONOEMBED
option failed for me. I found out this is because mono-1.dll depends on
a number of other dlls that can't be found in the search path.

Maybe you could add the Mono dir to the search path? Or instead hand the
command line over to mono.exe?

Getting past that hurdle I get this Mono exception:

 ... System.ArgumentException: FontFamily wasn't found.
