* missing various since

* Non working implementation since it's currently not possible to make it work as the web.xml mappins are done for the "standard" URL Scheme + the fact that the Error Handler is also currently hardcoded to use the "standard" URL Scheme (needs to be replaced by a Servlet).
* Even though it's not working, it's still useful to have it committed since it allows us to make sure the interfaces allow to contribute new schemes.
* Big refactoring to make it easier/possible to contribute new URL Schemes.

* Added missing dependency in Package Mojo so that it's available for all functional tests (ie it's in the base flavor)

This reverts commit 43164775.

- Disabled the feature by default and marked it as experimental until the performance problems are fixed.

* 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.

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-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).

* fix tests
