Reomved some logging & tidied up.
Added position and entry classes to every letter of every word, not just the first lot.
Added word clues, 'hint' button.
Fixed issues to do with currOri orientation detection. Based this off the data rather than the elements.

Fixed broken backspace/navigation stuff. My fault.
Minor derpage in nextPrevNav resolved.
Removed some console.logging.
