GtkSharp/generator/Property.cs
Dan Winship 5825f7f4fe Apply the parts of the generator reorganization from #69514 that
don't actually affect the generated output
	
	* generator/PropertyBase.cs: new base class for fields and
	properties (mostly containing code formerly in Property.cs).

	* generator/Property.cs: derive from PropertyBase

	* generator/FieldBase.cs: base class for fields (containing some
	code formerly in Field.cs)

	* generator/StructField.cs: class for struct fields (the rest of
	what used to be Field.cs)

	* generator/StructBase.cs: s/Field/StructField/

	* gnome/Gnome.metadata: hide a few funky _get_ methods that the
	generator is just now noticing, to preserve the old output.
