BigChange + JobLogic Integration

Keep BigChange and JobLogic aligned: when project management events happen in one, update the other automatically.

Example: when BigChange's "Watch Contacts" fires, WEXTL can "Add a Job Task" in JobLogic. BigChange has 10 triggers (including Watch Contacts, Watch Invoices, and Watch Jobs); JobLogic has 81 actions (including Add a Job Task, Add a Task Library, and Add Customer Contact to Job).
