Add support for element-type to GListModelissue-328

GListModel is an interface for creating typed, list-like containers. The
data stored is GObject instances, but it's useful to be able to annotate
the actual type, for both documentation and code generation purposes.

The annotation should be optional, to maintain backward compatibility.

Fixes: #328
