[DEV] A new Gnoll Coming in v2.3.0

Hey folks, here's some work I've done on the upcoming gnoll variant for the recently released caves quest.

Gnoll Guards are the common enemy for this variant, they lack the raw stats of gnoll brutes, but have a spear with some attack range instead! They'll do a lot of bonus damage if they can attack you from a distance, but also have trouble reaching around solid terrain. You'll want to use the environment to force them to get up close.
