[Sugar-devel] [RFC PATCH 4/8] Add a ListViewButton to the journal search toolbar.

[Andrés Ambrois]

Add a button to display the sorting options. Create a sort-property-changed
signal in the toolbar to notify the activity of changes.

Use a RadioToolButton for a future implementation of multiple journal views
(as described in the Journal Design Proposal).
