- Removed the unused sfx_ variables for the chainsaw sounds.

- 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.
