hud_bar_armor overflows with regeneration rune in CTF

[dsvensson]

When carrying the regeneration rune in CTF all armors can regenerate up to 150 points. This works fine for YA where 150 is max, and RA where max is more, but for green armor the armor bar grows outside its intended drawing region.

Maybe it could work similar to how mega works for health?

...not sure about the name though... color_ga_regen sounds a bit too specific, perhaps there are other mods that can go above 100 for GA? color_ga_(plus|over|above|overflow)?
