Bug 6261 [Revised] Consolidate patron toolbar include files

Bug 6261 [Revised] Consolidate patron toolbar include files

The staff client has two almost identical include files which
can be consolidated: circ-toolbar.inc and members-toolbar.inc.
This patch marges the slight differences between them and
eliminates circ-toolbar.inc, that being the one which was used
on fewer pages.

In order to accommodate the different "destination" variable
for operations which redirect back either to circ or patrons,
circulation.pl defines "destination" in the template.

Revision corrects a redirect error in setstatus.pl which
predates this patch but which never showed up until now.

To test, perform various operations from the toolbar on at least
two pages: circulation.pl and moremember.pl.

Operations: Edit, add child, duplicate, change password, print (all
options), search to hold, renew, set permissions, delete, update child
to adult, and export checked-in barcodes. In most cases simply
confirming that the link takes you to the right place is enough.
