I don't have beta access so I can't test this yet, but this should catch everything in the Deprecated_11_0_0 file in wow's official ui source as well as some stuff not mentioned but reported by users.
For charges, being full is the default state, so we need to treat full the same as health or mana being full. (ticket #231)
Also fixed the "target" variable never getting set on custom counters or custom counter bars because they were overriding the PLAYER_TARGET_CHANGED event that the base class was registering.
Also also fixed numeric display mode for custom counters not using the correct gradient scaling when the number hit 0. It was using the same scaling as graphical mode where 0 displays nothing and needs to be accounted for separately.
Now we pass in the options or defaults table directly to the helper class's getter methods since they're passed by reference and can be modified in place. This saves us creation of yet more tables and obviates the need to merge tables together.
