Since this base class is specific to Trello and not any job (e.g. Redmine, Travis, the Forge, etc...) I'd like to rename this to TrelloBaseJob before we merge it in.  If you don't object to this, do you mind if I simply layer a commit on top before I merge this into master?

Similarly, IssueJob should probably be TrelloIssueJob or something that indicates we're sending messages to Trello.

What do you think Ken?
