[Click] click element handlers

[Cliff Frey]

The way Roberto suggests is the highest-performance option. (pass one
element as a configuration parameter to another element)

If you want to actually use a read handler, look at the HandlerCall class...
and the cpHandlerCallRead definition in confparse.hh... and it should be
fairly easy to set up.
