VCL-919 - Allow customization of notification messages sent to users

siteconfig.php:
-modified Messages::getHTML: moved html for invalidmsgfieldspane to an earlier part of the html so that the box defaults to a higher position; it was a little out of the messages box
-modified AJvalidateMessagesPoll: no longer depend on usermessage_needs_validating (backend removed the entry); just look for and user message fields that were not set by the webcode and contain "invalidfields"

siteconfig.js: modified messages.prototype.updateInvalidContent: updated to handle invalid fields being separated into keys (i.e. message, subject, etc)
