* Modify the document tree page objects to support nested spaces
* Extend the TestUtils class with methods required for testing nested spaces
* Update the Document Index Tree functional tests

* Update usage examples
* Update translation keys
* Modify the document index tree to display nested documents

* Treat the value of the space field from the database as local space reference instead of space name.

- Introduced a workaround for the macro to still make sense until we decide if we remove it or not

XWIKI-12173: Add an option to merge the space home page node with the space node in the document tree

* Make sure the returned path is relative to the specified root.

[Misc] Improve test (and fix it since it was failing): the XWikiAllGroup that was used is a hidden doc and thus not visible by default.

+ speed up Panel tests (win 50 seconds by removing unnecessary waits)

* Fix remaining functional tests

* Add support for displaying 'New document...' and 'Upload file...' meta nodes in the document tree (needed by the WYSIWYG editor).
* Look only for default translations when suggesting documents (for the tree finder).
* Take suggestion data (e.g. resultHint, resultInfo) from node.data (rather than node directly)
* Add support to the suggest.js for specifying the type of each suggestion (used as a CSS class).
* Display 'No results!' when the tree finder has no suggestions.
* Scroll into view the node that corresponds to the selected suggestion.
* Remove SmartClient files and xwikiexplorer.js and update all the places where they were used.
* Enhance entityReference.js with a method to get an EntityType contant (enum value) by it's name.
XWIKI-5484: Problem to load the wiki pages tree/list (Link > Wiki page > "All the pages" tab) where there is a lot of pages
XWIKI-3796: No horizontal scrollbar for long page names in the treeview
XWIKI-11550: Document Tree macro doesn't properly work when using the "openTo" parameter and setting Hidden Docs to True
* Return the full node information when retrieving the path (rather than just the node id).
* When performing pagination, add the new nodes only if they don't exist already.
* Enhance openTo() to load the missing parent nodes (e.g. when they are 'hidden' by the pagination).
* Call the openTo() callback even if the path cannot be fully opened (some nodes don't exist).

* Create a jstree plugin for finding tree nodes using our own suggest.js
* Add support for suggesting documents, attachments and spaces to the document tree, using Solr with a fallback on database search.
* Add a new parameter named 'finder' to the {{documentTree}} and {{tree}} wiki macros that enables the finder plugin for the tree.
* FIX: openTo parameter was not working when showWikis was enabled.
* Enhance suggest.js to support:
** font icons
** referencing nested properties in the resultXXX configuration options (for JSON sources only)
** the results JSON can be an array (no need to specify 'resultsParameter' configuration option)
** specifying a source id in multi-source mode (in order to be able to apply different styles to suggestions comming from different sources)

XWIKI-11465: Add a parameter to the document tree to hide/show the entities for which the current user doesn't have view right
* Add missing dependency.

* Fix the problem in the tree widget untill it's fixed upstream.
* Escape the macro parameter values in DocumentTree macro and Navigation panel.

XWIKI-11465: Add a parameter to the document tree to hide/show the entities for which the current user doesn't have view right

* Use a stack to compute the document path recursively.

* Bulletproofing the code in case the user doesn't have the right to view the document.

* Add page objects and update tests
* openTo should not select the node because if links are enabled then it will follow the link.
