Jenkins - GitHub integration.

[Ian Boston <ie...@tfd.co.uk>]

Hi,
Jenkins is now building pull requests against
https://github.com/apache/sling <https://github.com/apache/sling/pull/130>,
so when anyone does a pull request, it will be built and tested with the
integration test profile.

Provided master is building without failures, and the pull request is good,
then you should be able to verify that a pull request has no regressions
without having to apply the patch locally and test.

At the moment, master is not building the integration test profile, as it
fails on 2 - 3 tests, so its best to check what is failing before deciding
if a pull request is ok. There is also a Travis based build which is
building openjdk6 and 7 both of which fail all the time, so ignore the
Travis build.

Finally, if you mention a SLING Jira ID in the pull request, the GitHub Bot
will comment in JIRA for you.

HTH
Best Regards
Ian
