[patch] Removal of GIF support

It really pains me to have to do this, but UniSys has given us no choice. Due to their claims that "Our patents cover both creating graphics and displaying (e.g., reading, decompressing) LZW. As such, a license is rquired to create or distribute products incorporating such capability." we must remove this support from XEmacs, and I am requesting that all of you who've downloaded GifReader please delete it. 1998-07-21 P.
