XWIKI-11611: Presentation Office documents (.ppt & .pptx) aren't displayed with LibreOffice 4.3.0.1+
* Upgrade the JODConverter version.

* Un-wrap the links generated from wiki syntax so that they are taken into account by jsTree.

* Improve setup so that $doc in script in wiki pages is rendererd properly

* Fixed Class Fan out

* Show the Attachments node when showAddAttachment=true, even if there are no attachments.
* Refactor a bit the code to remove duplication.

* Fixed test issue indirectly caused in DefaultContextualAuthorizationManagerTest

* Added unit test

+ Improved the framework for unit testing XAR pages (see PageTest and its usages)

XWIKI-6844: PR leak in Document#display(), exploitable by any registered user with 4 lines of velocity.

XWIKI-10118: Allow multiple column layouts on single page.

* Add missing dependency.

* Move the hierarchy mapping in a separate file to avoid duplication.

Revert "XWIKI-13468: The query used by the Document Tree to get the nested child pages is very costly"
* Too much duplication. Better move the hierarchy mapping in a separate file.

This reverts commit da8a821d.

* Proper fix.

* Update the database-specific mapping files.

[Misc] Reorganize properties for better clarify + add explanation about the stats app not being by default anymore (since users are asking)

* Define a new Hibernate entity, XWikiPage, mapped to a SQL union between the documents table and the spaces table. This new entity is used in HQL queries to fetch the Nested Pages hierarchy.
* Separate the Document Tree code that queries the Nested Pages hierarchy from the code that displays the hierarchy. Move the former from Velocity to Java components. This way the Document Tree doesn't requrie PR for querying the Nested Pages hierarchy.
XWIKI-13615: "one more" does not make sense
* Query limit+1 child nodes and display only limit if there are more left.
XWIKI-12909: openTo doesn't work when root is specified as relative reference
XWIKI-13225: Finder in documentTree not working
* Resolve the relative root and openTo parameters.
XWIKI-13183: Some document tree branches not translated
* Display the translated page title
XWIKI-12832: Add support for sorting the pages by their title in the document tree
* Sort by the raw translated title field (with fall-back on the default title and then on page/space name)

* Best effort (we do no recommend to use rel="external" anymore).
