WowAce

- click-cast frames don't rotate with bars (consider disallowing rotation on bars that support click-casting...)
- consider automatically replacing Focus/ToT health/mana modules with custom ones
- investigate why animations break at super low update frequencies for some people
- addons that attach extra bars (PlayerHealth, SnD, Threat, Eclipse, CastBar) are behaving inefficiently and inconsistently on update. Some are also calling SetBarCoord unnecessarily, which results in at least 4 WoW API calls (and C <-> Lua overhead?) each time. They should be brought more in line with how the default bar in IceBarElement updates, where possible.
