UX improvements.

* Text that refers to an object in TestMill is quoted using back-quotes.
* Application can be specified using their unqualified name when there
  is a manifest.
* On output, show applications without the project name.
* Add --full option to `ravtest ps`.

This change also mixes in Python 2.6 support. Any references to
format strings without index ("{}".format('foo')) are changed
to include indices.
