5.4 PTR Update

- Eviscerate data was wrong. Turns out Blizzard never fixed the data
from a stealth buff during beta. Everything matches dbc values now.
- 2 Ambushes won't fill a CP bar. Doesn't support anticipation-less
well, but it's good for the brief moment.
- Rupture only costs 25, not 35 energy.
- Removed old Sub code. No longer serves a purpose.
- FW multipliers improved. Could be better, but this is monumentally
better than it was a month ago.
- Shifted damage and energy with t16 4pc appropriately now.
