giladgo's work: allow editors to edit bill title
Merge branch 'master' of github.com:hasadna/Open-Knesset
in edit bill modal: move submit button to new line; add translations
edit bill: add logging, and return HttpResponseForbidden if user is attempting to edit without permissions
edit bill: don't render the modal if not needed (user has no permission)
edit bill: change logging to user id. too tired for encoding wars
Better layout for bill_detail form
