Subject: [PATCH] Improved check for skins and maps in the same WAD

The corresponding warning is shown for Doom I mods too. Good example of it is Hyena TC: http://www.doomworld.com/idgames/index.php?file=levels/doom/Ports/megawads/hyena.zip
Reduced chance of false positive for the mentioned warning
