expose current_gist from controller

we need this to create URLs (or, at least we need the gist id from it).
it seems sort of (?) reasonable, but maybe if we are acknowledging that
the controller is caching the gist, then it should be part of the
notebook model?
use the notebook.R URL instead of the github gist raw_url for the asset link

fixes #675
add ace's JavaScript webworker

this is kind of a monster at 10kloc, so we'll see if it causes
problems, but it enables cool stuff like jshint in assets

and we were getting console errors without it, so if we don't
want it, we should explicitly disable it
