First Content Patch

First two updates focused on fixing bugs, now it's time for a little bit of new content! Additions: -New enemy type, The archer. -New active ability that slows down time.

Fixes/Changes: -improved enemy pathfinding. Still not perfect, they sometimes get stuck, but it is much more performant. -weapons now don't stutter when moving. -swapped the sniper rifle and the crossbow as purchasable/available weapons. Now the three originally available weapons aren't all hitscan.
