Use My Documents/My Games/dhewm3 on windows

Browse source 
Includes savegames, configs, screenshots and so on.

And "My Documents" is actually CSIDL_PERSONAL, see
http://msdn.microsoft.com/en-us/library/windows/desktop/bb762494%28v=vs.85%29.aspx

This somehow matches the behaviour on Linux and OSX where this stuff is
saved in some kind of home-dir (e.g. ~/.doom3)

Taken (with kind permission) from Yamagi Quake II's Sys_GetHomeDir()
