fixed mistakes I made with github doing stuff.
most recent changes.
Now properly deals with periods. Colon/Semicolon probably will mess things up still.
no longer crash when hints run dry (gives "no more hints" instead)
submit hint input appears correctly, default hints no longer show up for answers that don't have hints, all hints for answer show up (limit later)
slight changes to hint showing during get_feedback
changes to make colon/semicolon/quotes in hint submission not mess up the feedback (replace : with a word, for example). replacement words are not elegant but they aren't anything someon would type in so they will be fine for now i think.
