Moved libphonenumber translations to layout.js. Moved html_entity_decode to hierarchyTree.js (only place used). Removed unused function.

Added needed styling for hierarchy tree to bootstrap.less so that the jsTree theme css doesn't need to be loaded (it breaks hierarchical facet display). Also added a translated "Loading" text with a spinner.

- XML still partially supported for legacy Blueprint theme support.

(Pull request was merged due to accidental button press -- not ready yet).
