Title: Make Form.Field template rendering context overrideable

Extract the current inline context into a method, renderingContext().
In this way, by extend()ing or overriding Form.Field.renderingContext,
one can use other data in the template.

I believe this would address the concerns in https://github.com/powmedia/backbone-forms/issues/120
