Subject: Add -nwtmerge option, which behaves the same as NWT's -merge option.
 What this does is load a PWAD, then search through the IWAD sprites list,
 removing lumps where there are lumps of the same name in the PWAD. The PWAD
 must then be loaded again with the normal -file option. This is needed to run
 TiC's Obituary TC: chocolate-doom -nwtmerge obtic2.wad -file obtic1.wad
 obtic2.wad -deh obtic1.deh Also add W_PrintDirectory debug function,
 W_AddFile changed to return handle.
