* Rework error handling. Mason's dhandler is no longer in charge of

   generating 404's; instead, the dispatcher catches when no views can
   handle a request.

 * Relatedly, don't bother catching, popping the buffer stack, and
   rethrowing on every error.  Instead, explicitly _don't_ pop the
   stack, and use the frames that remain on the stack when we catch it
   in the dispatcher to show a stack trace.

 * Rename 'mason_internal_error' to the more straightforward
   '/errors/500', and have ErrorTemplates do the right thing.
