NIHVIVO-646 Add cancelUrl parameter to submit tag in InputElementFormattingTags so that the cancel button can redirect to a different page from the form submission. Change cancel values in submit tags in vitro and vivo forms to "true" where previously they specified a uri, because the uri is misleading (it doesn't control the redirect location). Removed edit submission preprocessing due to problems with cloning.
