[lazarus] variation in implementation of evenments

[P Jean dit Bailleul]

In Delphi most event are implemented in 2 phases : a method recieve the
message (like WmClick, WmChange...), this method call a second method (like
Click, Change...) which is dynamic and respond to the event (by calling an
OnClick, OnChange...). This way it is possible to override those methods to
implement responds to these events.
I think it would be usefull to implement the LCL the same way.

To do so, someone (i can't connect to CVS) need to change the
TControl.DoClick to call a dynamic method TControl.Click which test
FOnClick and call it if needed. I also need the TCustomComboBox.DoChange to
be modified the same way.
