Bear Alternative form for low level cat strat (#2041)

This adds the bear form as an alternative form for druids with the cat
strategies. This applies to low level (<20) druids that have the cat
strategy applied. Reset botAI would not normally give them the strat,
because they dont have cat form, but if set, this allows more dps.
