Change interpretation of DOOMWADDIR to the classic behavior: a single directory path where an IWAD can be found. Add DOOMWADPATH as a PATH-style list of directories to search for IWADs. This is to maintain consistency/compatibility with other ports, and so that the DOOMWADDIR name makes sense. Subversion-branch: /trunk/chocolate-doom Subversion-revision: 828
