Bump version so we don't collide with the last npm release.
Use jsdom instead of directly contextify.

After some experimentation I've reached the conclusion that running
AngularJS outside of the context of a DOM is a fool's errand, so instead
we'll provide it with just enough DOM to keep it happy.

This removes the requirement for a patched version of AngularJS, and also
allows the $compile service to work out of the box because it is able
to create elements using our jsdom document as the owner.

The downside here is that a context object has considerably more startup
and memory overhead, but being able to use $compile is a key part of
most potential applications of this module, so we accept that overhead.
