* data/dbus/tracker-indexer.xml: 
	* src/tracker-indexer/tracker-indexer.c: Removed the "Reason" from
	the Paused signal since we don't have a reason any more. We are
	paused when we are told. All battery monitoring and disk space
	monitoring has been moved to the daemon status module and removed
	from the indexer so state is more centrally observed.

	* src/tracker-utils/tracker-status.c: Added a couple of command
	line options to "follow" the status of Tracker using --follow
	(instead of just returning to the command line after the initial
	query) and also to get more details using --detailed.

	* src/trackerd/tracker-dbus.c: 
	* src/trackerd/tracker-status.[ch]:  Added APIs to deal with
	pausing during DBus calls. Fixed a bunch of issues found here
	where we just weren't returning to the correct state after being
	paused due to DBus requests from apps or pausing manually from the
	user.
