5.4 PTR Update

- KS factors in the same artificial delay for AR+SB (used to represent
the tendency to not be able to cast it on CD), bringing the CDs in line.
- Glyph of Vanish apparently causes Subterfuge to proc twice. I'll
investigate how this affects FW uptime soon.
- Default latency has been moved up .005 to .03. Just playing around
with how it affects DPS.
