Door Update

Door works for player. Must open the door first, and then the player can
path. Tied into waypoints as long as door trigger is also present (Along
with Door),

Enemies are limited by closed doors atm (they were before as well).

Made door trigger start function Awake function since it was mainly just
making links, and not doing computational stuff.
