Small, balanced adjustments that would fix Monk's new kit

[Fritz_OS]

Brotherhood

- Damage buff now affects magic damage
- Chakras may proc from spells as well as weaponskills

This is the only straight up buff I’ll ask for, and it doesn’t affect our personal DPS; Brotherhood’s anti-synergy with magic users is daft – Battle Littany and Trick Attack affect everyone, and would still be more powerful buffs besides (which I’m not complaining about).

Limiting Brotherhood to physical damage makes Monk that bit less desirable in raid groups with casters, which almost encourages them to choose one or the other (which is unlikely to go in our favour). Reduce the Chakra proc rate if necessary to account for this change, but change it nonetheless.
