Removing the "handled" logic from the forms app, as it was impossible to reach after the new regex parsing was added. Also slightly tweaked the regex parsing to not include the domain in the search strings for the forms.  This was making llin trigger an issue form. Finally, adding a helper message to the forms app so that others can use this to generate helpful responses.  This is now implemented by the nigeria app, which will respond if nothing else does in the cleanup phase.
