Currently the terminal app readme gives improper information for running the autopilot tests. It's useful for new contributors to easily be able to build the project and run the tests.

Your task is to fix the README file, and expand the readme's to make it easier for new contributors.

For a model of readme's to follow, see the clock app (bzr branch lp:ubuntu-clock-app). Notice how there is a readme for testing, installing, developing, translations, etc.

Once your work is complete, please submit a merge proposal to the terminal app. See the student guide below for more information on working with launchpad, including submitting the proposal.
