Quest Tracker Background

1.0.3:

* In a scenario where the minimap icon doesn't show, an additional slash command has been added to hopefully provide an alternative configuration method:

        /qb set 75

  This will enable the Show option, will Lock the background to allow click-through and will Set the opacity to 75%; different opacity values can be used as desired

* Fixed some inconsistencies with the slash commands; they should work as expected now and the displayed values should be correct
