Link pane title to another page/url

Fieldable Panels Panes is lacking the option to link the title of a pane to another page or URL, like you can when you place a node or a view in a panel. I guess the difference is nodes and views already have paths.

Attached patch adds a link checkbox and a path textfield and makes the title in to a link in fieldable_panels_panes_preprocess_panels_pane(). There is no validation or filtering but I believe that should be safe as it goes through the l() function.

This seemed to be the simplest approach, but other thoughts I had were to use a link or node reference field in the fieldable entity and use that to preprocess the title, or alternatively provide this functionality in Panels, but I'm not sure how to go about that considering some plugins already provide linking ability.
