kohabug 2159 Improving "Lists" button list refreshes after adding/changing lists/shelves

Adding code to refresh "Lists" button lists display in OPAC masthead.inc

Adding javascript to force refresh of parent window to update "Lists" button menu

Adding query limits and ability to specify row count and offset in queries related to Virtualshelves.
Also added the ability to return total record counts for specified virtualshelves.

Adding C4::VirtualShelves::GetRecentShelves which returns a list of the most recently modified shelves for
a given set of parameters. This allows the user to be offered active private and open lists to add books
to in drop down menus while also allowing drop down menus to be limited to a reasonable length.
This also limits the shelves stored in the user's session to a fixed number. A further enhancement might
be to add a syspref to enable a staff member to define the limit. Currently it is hardcoded at 10 per
list type (private/public-open).

Adding pagination to list/shelf related screens

Moving refresh shelves code into C4::VirtualShelves::RefreshShelvesSummary and tidying up a bit

Correcting several inconsistancies in the shelves templates as well as handling shelf management on
the intranet side correctly.

Correcting "Add To:" drop-down list to show only lists the patron has permission to add to

Correcting a few C4::VirtualShelves::GetShelvesSummary API calls

Modifications for template consistancy

Breaking up a 1367 char line of javascript in opac-results.tmpl
