Make the thumbnail cache global rather than per-MailDisplay, since

	* mail-display.c (pixbuf_gen_idle, etc): Make the thumbnail cache
	global rather than per-MailDisplay, since content-ids ought to be
	globally unique. Also, don't leak content-id strings when the
	pixbuf generation fails, and remove pixbufs from the cache after 5
	minutes.
