Swapping layer 2 sticky and layer 2 toggle keys. Now that sticky works
as desired, it is possible to hold the sticky key down for short number
runs and it is now a more frequently used key that toggle. Also added
notes about mac keycodes that I found in search of play/next/prev
buttons. I suspect that codes need to be inserted into the USB data
stream to indicate that a media key is being pressed.
adding layout description and updated layout. removing unused layers
added a created by line per code review comments and moved the configurator link to come after the description
removed TODO comment and readded deleted whitespace as per code review comments
