- Added directory detection to the -file parameter. This obsoletes -dir, so that parameter is now gone. - Removed automatic ".wad" appending from FWadCollection::InitMultipleFiles() since it isn't needed and prevented files without extensions from being loaded. D_AddFile() already takes care of adding the extension if the name as-given does not exist. - Fixed: Loading single files did not print a newline in the startup text. - Fixed: A_JumpIf(InTarget)Inventory jumped if the check amount was greater than the item's max amount and the item was maxed. - Fixed: Some dmadds wads used zero-length sprites as placeholders. When you ran dmadds to combine it with the IWAD's sprites, they would be replaced by the IWAD's sprites, so when loading such wads, we should ignore those as valid sprites. (Thanks to entryway for finding this.) See 22ventry's 22sprite.wad for an example. - Replaced the use of autoconf's WORDS_BIGENDIAN with __BIG_ENDIAN__, since latter comes predefined by GCC. git-svn-id: http://mancubus.net/svn/hosted/gzdoom/trunk@433 b0f79afe-0144-0410-b225-9a4edf0717df
