Fixed a bug I introduced by renaming my match buttons. Changed the colors of my icons.
Got my nback settings menu to be interactive: has an active class on the nback setting that is active, and setSettings looks for the active nback setting to define 'n'.
Removed my redundant n-back form input. To clarify, in my last checkin notes, where I used the term 'n-equals setting', I meant to say 'n-equals class'.
