Indoor Sprite Sheet update

I've uploaded a slightly updated version of the demo here. I photoshopped the indoor sprite sheet that was original made in Tiled. This was to fix pixels not being perfectly aligned how I wanted them, plus just minor graphics improvements. Very minor stuff that probably only I would even notice.

I also added invisible actors with triggers. This lets me have hidden easter eggs when you walk up to and interact with the glass displays, plus it allowed me to give the player to interact with the NPCs behind the desk, but from on the other side of the desk.

I also updated the movement pattern of one of the NPCs as her sprite would previously hit a wall and then just quit walking afterwards.
