#94 initial setup and script creation for the spider tank burrowing/tunneling state.
#94. added two new methods to get a random relocation position or to get the nearest relocation position to the player.
#94. basic scripts setup for burrow state. going to start testing soon. not sure how to go about transitioning to the state, though.
#129. general optimizations to the player movement and dash. removed all timers (using invokes instead), removed other unnecessary variables.
#129. toned down the dash settings so the player doesn't move so fast - definitely helped reduce going through walls. further improvements to the PlayerMovement script for optimization and less chance of going through walls. increased the size of the box colliders on level walls - reduced going through walls more than anything else.
#94. Burrow state complete. All that's left to do is add some kind of animation / visual effect which the script is setup to do so.
#94. Cached the mesh renderers for a performance improvement.
