Updates and Thoughts for Release 2.0

[zz85]

Earlier this year I came up with a list of stuff #22 I thought could be work on.

After a long break, issue #35 prompted me to work with the new autofix jscs and with that integrated I think we are ready for the next release already.
#6 was also an interesting idea, but after my more recent exploration of it (see mrdoob/three.js#6654) I'm inclined to have these features implemented in other editors (eg. https://github.com/zz85/campjs-livecode) than to bloat a much simpler editor focused on code style.
#27 and #38 are pretty valid use cases, definitely would want them implemented.

Of course, supporting presets in #39 is a quick win, maybe i'll decide to add a jscs config editor in future.

Also, maybe adding an immediate "Autofix" button and switching the current "Autoformat" button to perhaps "Compare Formatting" or something
