Drums/Monk buff + Symbiosis

GitHub won't let me open two pull requests at the same time so ...

Part 1: Monk buff overwrites leatherworker's drums

Part 2: Druid Symbiosis tracker
This one is rather annoying, as /cast [@foo] Symbiosis fails with "Invalid target" error so manual buffing is (currently) required. Seems to be a Blizzard bug ... However, I keep forgetting to re-buff so I added this nonetheless ;)

Hopefully Big B fixes this soon(tm).
