Fix BL coefficient, per tick damage is 150%
Change grenade multiplier from 0.5 to 1

I figured that putting them at 0.5 is probably a bit too restrictive,
considering they really do all hit in AoE scenarios, and for anything
larger than the skeletons I tested on.
Add pre-calculated Ambush HP multiplier
Add in full fire rotation
Add lots of example models I used for calculation

These are probably not hugely reliable but can serve as a decent guide
on how to write your own models.
