Hullaballoo!
Movement and interactivity fixes/additions
* Movement now works 100% correct
* Added obstacles and collision
* Added locks map and interactivity

Bugs:
* Not sure why doors only open with the pressure plate, they shouldn't be connected
* Figure out how to make doors activate others without getting stuck open
Connection/lock corrections, like not counting '0' groups. Depth corrections.

Remaining bugs:
* None, really… Just things not doing what I want them to. A lack of features!

Things wot need doing:
* Get the player to grab boxes and drag them around (so you can pull them through the hallways).
* Delayed doors; the current system can make doors open in sequence but not close.
