Trigger steps could link to triggered builds

[jaredgrubb]

Currently, there is no information pushed back to the Trigger step about any of the triggered builds. Doing so would allow many nice features:

• ability to add URL links between trigger steps and the triggered builds (in both waterfall and in detail view)
• ability for status targets to retrieve more details about those builds (for example, include URL to triggered build summaries, or even traverse deeper into the triggers to create nested lists of information about a build).

This definitely should work when waitForFinish=True, and in theory could work even for waitForFinish=False, but I'm not going to attempt that yet.

Marking as 0.8.6 as I do have a patch ready for review and should be generating a pull request shortly.
