Re-adding the rvm patch I reverted previosly because the tests didn't pass.

Revert "Revert "Merge pull request #40 from mynewsdesk/rvm". Can't get tests to"

This reverts commit c061138878dc0979305bb2682f980f6acfff846b.

Fixed a bug introduced in 0.7.0. The TEST_INSTANCES env-variable are now present again when running before_run scripts.
Removing mostly useless runner test.

The runner and job code should be rewritten from scratch. This spec is
way to fragile and takes more time to maintain than it saves.
Prep for release: increased timeout.
Don't stop the runner when job result update fails to post.
Increasing the time between updates to lessen the load on the server.

We've had problems with timeouts with only 10 workers. Some people run
almost 100 of them :).
Upping version
Update changelog for 0.7.3.
Merge branch 'master' of github.com:joakimk/testbot
