Added helpers for conversion

Now has helpers for conversion of points between world space and mask
space.
Refactored names and functions

GetAngleOffset is now static, spawnPoint is now encapsulated.
Refactored names and functions

woops, supposed to be same as last
Modified test data

Testing for spawn point data, more loops.
Replaced GameObject reliance for collisions with sensor system, added rudimentary 360 degree movement

The player now calculates collisions from a list of points which are
continually updated to stick to the game object's position. This sensor
data is recalculated based on offset values added to the file and the
wall mode. As a result, adding basic 360 degree movement was easy. Big
milestone here!
