Titan Panel Controller for WeaponRebuff (Redux2)

Displays the state of WeaponRebuff (Redux2) and allows control through the Titan Panel Plugin controller.

NOTE: Sadly, most of the pre-2.0 functionality that worked so well is toast thanks to Blizzard; however, the convenient display is still helpful to a point. Added are functions to show the WeaponRebuff Buff Selector (for easy buffing choice) and to toggle show/hide of WeaponRebuff.

In lieu of click/shift-click buffing I made clicking the Titan Panel plugin toggle show/hide for WeaponRebuff itself so that one could run a minimalist layout for WeaponRebuff itself (putting the two buttons near the position of WeaponRebuffFu) so that it would be click(toggleon), click(buff), click(toggleoff). Not as good as it was but better than nothing.
