[Radar] Code overhaul

Brings a new "voice status" column, showing voice use as active speakers floater does.
- Shown by default, look in Extras tab to hide it
Attempt to blend and fix the visibility of the yellow for shout range.
- Requires user feedback, looks good on default and gemini to me

Refactors pretty much all of the code in the avatar list
-Less duplicate vars, less wasted space, more consistent spacing conventions, eradication of BOOL use.
We no longer add (or even evaluate what should be in) icon columns that are hidden
- This prevents icons from showing up even when their columns are hidden.
Minor work on focusing out of draw avatars, though that still won't work, sadly.
