Support Continuous Integration servers

[xolvio]

Provide a command line to do --single-run, which would:

• Fire up RTD services
• Run a single pass of all the unit / acceptance / coverage tests
• Gracefully shut down all the services (option to keep servers running, like Selenium)
• Return an exit code for CI servers to deal with
• Output a report that CI servers can publish

Try the pull request, should solve all point but:

• Gracefully shut down all the services (option to keep servers running, like Selenium)

Tested locally with Jenkins, all results are published as junit reports into path test/rtd/reports

Thank you very much, I'm just looking at merging this...

Where is the pull request ? Maybe that issue can be closed ? I hope that when I solve all my issues with RTD, Travis will be able to execute the tests without complaining :)
