Use _.bind() for better compatibility

I ran into an issue where the iOS WebView for older iOS versions doesn't have Function.prototype.bind()...using _.bind() instead solves the problem and works fine.

Fixing _.bindAll(this) call to be compatible with underscore >= 1.5.0

Documentation regarding the change here: https://github.com/jashkenas/underscore/issues/992, here: https://github.com/jashkenas/underscore/issues/1033, and here: https://github.com/jashkenas/underscore/commit/bf657be243a075b5e72acc8a83e6f12a564d8f55

From what I can tell, the _.bindAll() method was just to handle binding the event handlers to the instance of `Backbone.Firebase` that was being used to sync data to and from Firebase. The binding can therefore be assigned inside the .on() call, and the _.bindAll() method can be removed.
