[Brewmaster] - Stagger and Brews Tracker

This weakaura helps you keep track of your brews and stagger economy.

Screenshots show three situations -

1: Three or so seconds remaining on ironskin brew, about 10-20% of max health in staggered damage, and two brew charges ready. (third charge almost recharged)

2: No ironskin brew active, negligible staggered damage, and two brew charges ready (third charge about half recharged)

3: A long duration of ironskin brew is active (bar is green), about 10-20% of max health in staggered damage, and 3 brew charges ready (4th charge about 25% recharged)
