changed fillin text slightly
getting the hang of using medium.js
understanding medium.js css stuff
added option to use medium.js instead of simple contenteditable

but it caused some placement issues and i want to move on to split screen stuff before i return to it
added split-screen and fixed medium.js bugs

so we have something that doesn't look totally terrible now!
i mean, it still looks pretty bad
but not as bad
Merge branch 'master' into gh-pages
