Fixed popUpBg image not displaying in game.

this was not so much a problem with loading this type of texture,
more so it was the fact that the file name had incorrect capitialization in the theme.ini file
causing the png file to be not found on *nix systems.

Ive implemented a workaround that will solve this without the theme files needing to be changed.
so the game is now tolerant of themes having incorrect case in the filenames.
