More stuff

Lots of updates over the past few days. As usual I keep adding new gameplay mechanics to support my planned narrative. But several core systems still need to be put in place before I can start to add quests objectives.

Here's a (incomplete) list of newly added features:

- Indicators to show which enemies are alerted to you and whether they have line of sight

- Free 360 degree rotatable camera with reset button (it was previously locked)

- Moveable objects that can serve as strategic combat elements or puzzle pieces

- Better NPC pathfinding and behavior

- Better player character behavior ^^;
