Make CPWL_Timer simpler.

Remove CPWL_TimerHandler, which was an object that served two
purposes: as an interface to dispatch a timer event, and as
an interface to obtain a systemhandler. The second isn't required,
and the first is better provided by a nested pure virtual class.

Also remove the start/stop timer mechanism, timers should be
cancelled by merely deleting them.

-- CPWL_Wnd now does not get a timer by default, only specific
   subclasses will have one.
