(GetHandlerName): New abstraction of name handling.
(GenerateDecls): use GetHandlerName.
(GenComments): make private.
(GenHandler): New. Generate custom event handlers and args.
(Generate): use GenHandler. Pass args type to SignalHandler.

* codegen/defs-parse.pl (get_sighandler): gen the helper class. arg
passing and return value handling need beefing up still.

subclasses. (ctor): prune down to two params.

Only generates the delegate so far.
* codegen/hardcoded.defs : Added a stub for Gdk.Event.
* gdk/Event.cs : Killed, now a generated struct.
