Sends overlong summary which rietveld rejects

[Martin Packman]

When using lbox to create a rietveld version of an already existing launchpad merge proposal, it failed at the submission step with:

    2012/06/19 15:35:55 error: Failed to send patch set to codereview: Issue creation errors: {'subject': [u'Ensure this value has at most 100 characters (it has 204).']}

The first paragraph from the merge proposal, which lbox sets at the summary, was longer than the server was prepared to accept. (Also tried and failed to send several times, so lbox has no way to distinguish transient errors from this kind of bad request?)

Probably goetveld should just truncate the subject if it's given something overly large.

This was fixed at the time after a few helpful exchanges with Martin.
