Commit 8ff71d3f8567e68f925a9300f73b8e58cccc39eb

Implement methods to come near generic collections interface.

The GetRow method returns an array of objects similar to the foreach
statement on the model.

The Find method implement the collection-style Find function, with a
predicate.

The RemoveAll method, directly inside the ListStore class, implements
predicate-based removal of objects.
