Tuesday's goblinAmerica Improvements

Hi everyone. Here's a patch with some tweaks and bugfixes:

• Improved audio handling for aggressive solar goblins.

• Fixed a bug preventing goblins in some areas from attacking you as ferociously as they should be.

• Reduced trembling on incapacitated moon imps.

• Improved explosions of explosive blast barrels to behave and explode more consistently.

• Fixed bug causing odd head rotations among strangers with guns.

• Fixed bug causing crossbow bolt to do terrible things.

• Removed bad seam from a cliff in the mountain.

Thanks.
