Replace the Range functions from the compiled version of Annotator 1.2.x
with the latest CoffeeScript source from the v1.2.x branch of Annotator,
plus the fix added in b3056d27

This includes fixes for BrowserRange#normalize from
https://github.com/openannotation/annotator/commit/9bec776511a717ef944b36ed7cca3d107bd95c88

In addition, this removes the dependency on the Annotator framework from
annotator/anchoring and the highlighter, getting us closer to a point
where we can remove the dependency of the annotation layer on Annotator.

Fixes #109
