This PR is handles the changes required to support envelopes. The new envelope editor/signing page will be hidden during release. The core changes here is to migrate the documents and templates model to a centralized envelopes model. Even though Documents and Templates are removed, from the user perspective they will still exist as we remap envelopes to documents and templates.
