Code review comment for lp:~frankban/juju-quickstart/env-manage-edit

*** Submitted:

Implement the environment create/edit view.

Add a cli/forms.py module including helpers
to create and handle Urwid forms.

Allow for creating a new environment from the
env_index view.

Implement the env_edit view, used for creating
or updating environments.

Fix a corner case in envs.set_env_data: delete
the env_db default key only if the environments
has been modified.

Tests: `make check`.

QA: start the demo app
(`make` and `./cli-app-demo.py).
Use it to edit existing environments and
to create new ones (ec2 and local).
Check form errors are correctly handled.
Exit the demo app with either ^X or
selecting an environment to use. The
demo app should show changes on exit,
and notify whether a new db has been saved
and/or an environment has been selected.
