Bug 22191: Add column configuration to libraries administration

This patch adds column configuration to the table of libraries
in administration. No new defaults for the table are defined.

To test, apply the patch and clear your browser cache if necessary.

 - Go to Administration -> Libraries
   - Test that the "Column visibility" button works to show and hide
     columns. The "actions" column should be excluded.
   - Test that export options (Excel, CSV, etc) exclude the "actions"
     column.
 - Go to Administration -> Columns settings and edit the default
   configuration of the libraries table. Confirm that these
   changes are reflected in libraries administration.
