Bug 16080 [Revised] Remove unused images from the staff client

This patch removes images from the staff client templates which are no
longer used.

To test you must (as of 2016-04-22) apply the patch for Bug 16241.

Apply the patch and search for references in the Koha code to
the removed images. You should find none.

The staff client CSS file has been updated to remove obsolete references
to image files. These old styles were made obsolete by the switch to
Font Awesome icons.

Revision removes reference to glyphicons-halflings-koha.png from
circ/offline-mf.tt
