Also, avoid setting FLAG_INHERIT_COLUMNS for queues which do not inherit
from another queue.

Adds the UI for sorting and creating custom sorting options. Custom
sorting options can be used for ANY custom queue. Custom sorting has an
ascending priority. Meaning the top sorted field option is sorted
first.

* 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

This fixes a problem where viewing a queue with no defined columns would
result in attempting to add columns to the queue, which would result in an
incorrect SQL statement and an email sent to the administrator. This was
ultimately moot because columns are not added directly to the queue anymore.

Quick configure action menu is placed next to the title of all custom
queues.

HTML/CSS only needs php.

Queues can elect to use the columns from a parent. This is enforced by
default for saved searches and queues not defining any columns.

* Fix wrapping issue combining truncated fields with annotations
* Only support criteria inheritance for queues with a parent

The lclip truncate method allows for trimming the beginnging of the text.
This trimming will only work properly for left-to-right languages because it
changes the CSS `direction` property. Writing a rtl language ltr will
probably not be legible.

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.

* Add relative and full formats to the filter list
* All dates in queue are database-relative
* Fix very odd rendering of conditions in queue table
* Fix "clip" truncate mode
* Re-implement background color for Priority column
* Allocate no space for hidden annotations
* Add checkboxes to queue preview for closer resemblance to ticket queue
* Add default formats to initial date columns

And, fix bad width on new open queue
And, fix bad criteria on install

This allows for less work when designing new queues. The column design—the
data definition, annotations, and conditions, are saved with the column. The
heading, sort order, and width are set when the column is associated with a
queue. This means that changing the behavior of a particular column will
mean not having to redo work for each queue that uses the column.

This is a new concept for many-to-many relationships, where the extra fields
from the middle table can be overlaid over the related model using the
AnnotatedModel paradigm. The overlaid fields are writable and updates are
saved to the middle model.

This is performed using a new ::wrap method of the AnnotatedModel class.

AnnotatedModel::wrap($what, $overlay, [$class])

Which will create a new class which is a subclass of `$what`, and will have
the extra properties in `$overlay` accessible as normal properties.
`$overlay` can be an array or a VerySimpleModel instance. The latter is
required for writable overlays.

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