[ Mike, this is everything I wanted in for the release. ]
* generator/StructBase.cs: Generate field accessors for wrapped
types (opaque, object, and structs/boxed). Bitfields, unions, and
arrays are still unsupported for accessors, and are probably marshalling
incorrectly. But this is enough to get events working (see example
in sample/GnomeHelloWorld.cs).
* parser/Metadata.pm: Support a "delete" directive, and set metadata
on structs and boxed (previously was only checking objects and interfaces).
* parser/Gdk.metadata: Delete bogus entries GdkWindowObject and
GdkPixmapObject (more evil drawable stuff.)
* sample/GnomeHelloWorld.cs: Show an example of how to use marshalled
events, in our selection callback.
