Title: Make log able to indicate how object was created.

Per story [55814440](https://www.pivotaltracker.com/story/show/55814440). Now allows passing an argument to `log_event` helper to indicate where the change was made from; as of this commit, only used to indicate an import. When events are displayed, this will then be indicated if one was given.
