- added bar/bg visibility options to mirrorbar, castbar, targetcastbar

- shuffled bar/bg visibility options to show up after the Enabled option and to be disabled if the bar is disabled
- removed OnUpdate registration for mirrorbar since it handles OnUpdate itself
- fixed a potential nil access in the DogTag fontstring stuff
