Subject: Exit with error on startup if using the wrong IWAD.

Having multiple binaries can cause some confusion - some users try to
run chocolate-doom with hexen.wad, thinking it is supported. Add a
startup check that makes sure the user is not trying to start the game
using the wrong IWAD file for the binary being run.

This fixes #382.
