Jump n' Jitter

Incremental improvement tackling a couple quality issues:

• Players have reported a drop in framerate in some of the forested areas. While I haven't eliminated this issue completely (yet), the issue shouldn't be quite as bad, as I've pruned the forest in the areas that were worst affected.

• Goblin no longer does "Bugs Bunny style" mid-air running. lol the right version of this would be cute, but this version wasn't, and the "footsteps" sound mid-air was sloppy rather than fun. Fixed!
