Added several files to .gitignore from http://kleber-swf.com/the-definitive-gitignore-for-unity-projects/
Added some movement functionality
 -Can now move left as well as right, with a public toggle
 -Limited the number of times you can jump - force applied on jump & max jumps are public

Added an 'autoscrolling' left boundary. Rough, but somewhat functional.
 -Left wall slowly moves the right. Velocity change can be set in the editor.
 -Camera's min X value is set to the wall's position plus a bit so the player can barely see the wall coming up on them.
