[REF] web: Control panel Owl

Refactoring of the control panel with the Owl framework.

The MVC structure of the control panel has been changed to a 'component <-> model'
relationship. As such:
- Removed the old control panel: view/model/controller/renderer
- Created a new Owl Component (ControlPanel)
- Created a new class: the Model (an Owl Store did not fit here) and a newly
  designed ControlPanelModel extending it

Refactored all inner subcomponents, including:
- Pager
- ActionMenus (peviously SideBar)
- Filter menu
    > Custom filter item
- Group by menu
    > Custom group by item
    > Removal of groupby_menu_mixin (and refactored graph controller in sibling commit)
- Time range menu
- Favorite menu
    > Custom favorite item
    > Moved the favorite menu registry to the favorite_menu file
- Search bar
    > Removed and splitted auto-completion dropdown logic between the new SearchBar
      Component (descriptions) and to the new ControlPanelModel (domains).

The templates (all in web/base.xml) have been adapted to the new standards. Most
of the DOM structure remains unchanged with some occasional improvements (replace
hiding with not rendering, removed pointless wrapper divs, etc.).

+     * Control panel model
+     *
+     * The control panel model state is an object structured in the following way:
+     *

+     *-------------------------------------------------------------------------
+     *
+     * The keys are stringified numbers called 'filter ids'.
+     * The values are objects called 'filters'.

+     * Each filter has the following properties:
+     *      @prop {number} id unique identifier, also the filter's corresponding key
+     *      @prop {number} groupId the id of some group, actually the group itself,
+     *                     the (active) 'groups' are reconstructed in _getGroups.

+     *      @prop {string} type 'filter'|'groupBy'|'timeRange'|'field'|'favorite'
