fsm.el is now in GNU ELPA, so let's use it if it's installed. Also,
let the jabber package depend on it.
Keep a copy in jabber-fallback-lib directory, and use it if necessary.
Notably, this one is still compatible with Emacs 23.
This directory should never be added to any load path, since
jabber-muc-nick-coloring.el explicitly specifies the directory when
referencing hexrgb. We wouldn't want to override any newer,
separately installed, hexrgb.el.
Adding this file should make life easier for emacsmirror.
