Graveeater:
	- make enable state persistent again
	- this will store the data on a per char basis (which is much more sensible)
	however, this might cause you to lose your settings (but anyway, there are not that many settings)
	- sometimes guildxp data is not present, this should improve this
	- remove left over debug stuff.
	- fix rested xp. why on earth would the function return nil if it means 0?
	- fix tooltip
	- major bug: level returned by GetGuildFaction is offset by one to data table
