Fixing the broken parts of ClassicRaidUI

[Vlad]

So basically by re-enabling the "hidden" features it seems that the frames created and the targeting of "targettarget" and "targettargettarget" are blocked, you can't hide/show them in combat, I mean, is there a secure way to reenable these or? I miss the old UI, it was really nice to drag the MT or MA units into their own frame on screen, it's ingenious!
