Added Autocapture Mode that does exactly what was asked for in issue/request #14 -- although I think two things should be done further: a) minimum time elapse for a new note to be created rather than just going back to where you were (the 'oops, I nicked the home button' scenario) and b) true cancel functionality in the `newNoteController`.
