Add charge

Becca.  The template shows the Charges Register heading when 'charges' json exists in the template.  If the casework frontend sends empty charges json, then the heading will still show.
We may end up having different date filters, in which case we would want to be more specific with the name, i.e. full_date_format
Would this filter be something that we would want available to other modules? Just a thought about code reuse :)
