First attempt at adding Travis CI and coverage to the project.
Update .travis.yml (previously some stupid options where preventing the tests from running). Add a minimalist README with Travis and Coveralls badges.
Start the X server on Travis. Add a README.md with the badges and removes the badges from the standard REAMDE.rst.
Fill REAMDE.md
Remove stupid import in forms.__init__. Add watchdogs and configobj as dependencies to the Travis install.
Fix travis install watchdogs->watchdog
Fix last import errors. (watchdog might still fail.)
Add some protection in tests based on watchdogs.
Skip test relying on watchdog on travis (will investigate on linux back in the lab).
Modify travis.yml to actually run tests with coverage so that coveralls get something to report.
