Title: Fix #1584 - Create default Backbone.history.

There may be a perfectly good reason to create `Backbone.history` lazily, but I couldn't find one in the issues since it was included with the [first draft of controllers and history][draft]. It seems to me that this doesn't significantly change any functionality and it prevents the error described in #1584 (which I agree is surprising when it's first encountered).
