This removes a significant number of queries used to render the drop-down
menu for the queues.

Each queue displayed on the page previously required a database query to
determine its children. This patch changes the strategy to fetch all the
queues and organize them as a tree. The tree can then be walked as the menu
is rendered and does not require any further queries.

On my test system, it reduces the number of queries for the ticket listing
page from 56 to 46.

* Drop per item edit and delete links
* Add drop-down links for edit and delete after queue title
* Fix crash on queues with keyword searches
* Fix menu collapse with several top-level queues. "Search" and "New Ticket"
  are always shown on the nav bar
* Update queue `path` on update
* Include cascaded parent's criteria when displaying inherited criteria
* Show inherited criteria on saved search edit dialog

Queue modifications remove fronted quick queue manager for admins,
modifies the width of the queue dropdown and adds better nested
dropdown for queues admin i.e. multi level dropdown instead of
originally the file tree style. Optimizations for IE9 and up (screen
shots to show IE9 sauce labs test). Additional minor design changes in
the dropdown menus.

This adds support for adding "personal" queues underneath any top-level
queue with automatic criteria inheritance.
