Fix an infinite loop, and disable twitter updates

Fix an infinite loop, and disable twitter updates

	* lj.el (lj-get-cookies): Fix infinite loop when flavour is auto.

	* lj.el (lj-post): Don't attempt to update Twitter.  It's broke.
	Erm, I mean that SXEmacs/LJ twitter updating is broken, not that
	Twitter itself is broken... at least not all the time. :-P

	* lj.el (lj-version): Bump.
