Discord Unit Frames for 4.3 (4.0.1a)

It's back.

This is a 4.x update of Mikey2k's update of Lozareth's highly configurable unit frame addon. At this stage I've only fixed what I've needed to get it working for me with no optimisations. If you have problems I will see what I can do but no promises.

This is my first attempt at LUA coding in any way, shape or form so it's definately use at your own risk, all care no responsibility, your experience may vary yada yada yada.

NOTES: I only use DUF for solo and 5 man instances so it is completely untested for any other mode of play.

I've hade to make add couple of FizzleFudges (commented) in order to get the options window to work.

Opening the options window will cause your frame rate to tank until it's closed again (If I find time I will see if this can be fixed) but for the most part setting options seems work but it has not been extensively tested.

** Change (4.0.1 - 4.0.1a) ** Because I couldn't figure out how to set the default unit when the options frame is first opened this could throw an error if any other button was pressed before selecting a particular unit. This is now fixed in version 4.0.1a
