Restore facet and view ordering, remove jquery-ui

The move to the new multi-select widget brought in a new sortable plugin that conflicts with jquery-ui. This broke drag and drop for facet and view placement.  This fixes that, and also includes a rewrite of the editor components that use a slider to use the noUiSlider that exhibit uses.

In the process, JQuery UI is removed as a builder dependency, and the container setup code is streamlined.
