Bug 19608: Move admin templates JavaScript to the footer: The rest

Bug 19608: Move admin templates JavaScript to the footer: The rest

This patch modifies the staff client administration templates so that
JavaScript is included in the footer instead of the header.

To test, apply the patch and test the JavaScript-driven features of the
modified templates: All button controls, DataTables functionality, tabs,
etc.

To test the changes to localization.tt you must have more than one
translation installed. Go to admin/itemtypes.pl, edit an itemtype, and
click the 'Translate into other languages' link.

To test the changes to sur_modmapping.tt, go to admin/z3950servers.pl
and create a new SRU server. Click the 'Modify' button next to 'SRU
Search fields mapping'
