* remove useless @since

* Use the refactoring script service to delete the application because otherwise we risk deleting the space preferences before the application pages, thus loosing the delete right.

* Create the application data and code home pages
* Register the application translation bundle at wiki/user level depending on the user rights, instead of using ON_DEMAND

* remove a css rule which seems not usefull anymore and the results looks bad

[misc] fix typo

Fixed

- Issue tracker pointing to the current Top level project

XWIKI-12794: The tree for a subwki element in the breadcrumbs displays the main wiki's documents instead of sibling subwikis
XWIKI-12795: The tree for the home element in the breadcrumbs does not display the full path
* Show the wikis nodes when the first path element is from a different wiki (compared to the last path element)
* Use the farm root if the path element represents a wiki.

XWIKI-12784: EntityReferenceTree doesn't support sibling nodes with the same name but different types

* Prefix the table alias with 'prop_' to avoid conflicts with SQL reserved keywords.
* Add unit tests
* Extend PageTest to be able to load more pages and to be able to add a (mock) Velocity tool to the Velocity context.

XWIKI-12798: Unable to import office documents

* Don't use @import anymore.

(cherry picked from commit 0d292b9c6e7ae5c0cee59958dfcad34f2ff195a5)

* Escape the wiki syntax
* The Class Wizard should create xclasses having XWiki 2.1 syntax.

- Fixed the display of the server path value when not set and not autodetected
