[GRASS-dev] Problem with font selection in gis.m on Windows

I lifted this from Init.sh, where it checks for things like Mingw and
Cygwin, so I thought it would work with windows. If it doesn't, I guess it's
pointless to have it in Init.sh too.

As the current font selection is done, I need to know if a Mac, Windows, or
other system is running to know where to look for fonts. If uname doesn't
work on Windows, I don't know how to find this out.

If there is no other solution, I'll try to implement an alternate kind of
dialog, using a listbox and the new and improved freetypecap file, like I've
done for the wxPython GUI.
