Always show nameplates in arena

When enabled (for either arena, battlegrounds, or epic battlegrounds), and the player enters that zone, this will automatically turn on the “Always Show Nameplates” option.

It will also turn “Always Show Nameplates” off when the player exits arena (only if the option was off prior to entering)

no setup required. 4 settings: enable/disable for arenas/bgs/epic bgs, one if you want the addon to display to your chat window when it is toggling the “Always Show Nameplates” setting (which is mostly for debugging)
