Bug 20809: Link patron image to patron image add/edit form

This patch modifies an include file so that it is possible with edit a
patron's image on any patron-related page which uses that include.

To test you must have the patronimages system preference enabled.

Apply the patch and open any patron record for viewing.

 - Hover the mouse over the patron image.

   - If the patron has a previously-defined patron image, should you see
     an "Edit" button appear. Clicking the button should display a modal
     dialog titled "Edit patron image." Test that the "Upload,"
     "Delete," and "Cancel" buttons work correctly.

   - If a patron has no patron image defined, you should see an "Add"
     button appear. Clicking the button should display a modal
     dialog titled "Edit patron image." Test that the "Upload,"
     "Delete," and "Cancel" buttons work correctly.

This process should work from any page which shows the patron sidebar:
Check out, Details, Fines, Routing lists, Circulation history, etc.

Patch works as described.
