- Fixed map name checks in idclev, hxvisit, for +map and the titlemap. - Changed handling of Zips so that the patches/, graphics/, sounds/ and music/ subdirectories no longer are placed in the global namespace. Instead new namespaces are defined. These namespaces aren't merged, however and searching in them either returns a lump inside it or one from the global namespace when it doesn't come from a Zip file. Proper order of files is still observed though. As a result proper use of the directories inside Zips is strictly enforced now so that for example anything used as a patch must be in the patches/ directory and won't be found anywhere else.
