[Feature] Alternate Party Frames

[DDjusD]

Describe the feature

I prefer the way you handle unit frames much more than the built in way already in Cell and think it would be nice to have all unit frames be more uniform in setup. Your unit frames offer more in the way of customization than Cell does as well as some features that would be nice for party frames like the cast bar and alt power bars (for stuff like horrific visions and such).

Describe the implementation

Basically, just party frames that can be customized the same ways you can for the player/target/etc frames you already support as well as the features yours have that base Cell doesn't. Mainly, the bar textures, cast bar, alt power bar, and custom text. The status icon (the resurrection one) and aggro indicators would also be nice for keeping an eye on things.
