* Fix javadoc
* Allow XE to overwrite the default WYSIWYG editor (use CKEditor instead, for instance)

* Check the standard configuration first and then the custom one. This allows the custom configuration to specify the default editor when there's no one configured.
* When there's no editor available for the specified category try to return the first editor available for the specified data type.
* Use the "text" editor as the default XDOM editor when there's no configured XDOM editor

* Add missing module.

* Fix the GWT WYSIWYG editor template.
* Bundle the edit module in the default distribution
* Bundle the edit module implementation in the package created by the pacakger plugin.

* Fix quality build (test coverage)

XWIKI-12498: Instance output filter should support begin/endWikiDocument without corresponding locale/revision

* Add helper script service methods to retrieve the default Text and WYSIWYG editors
* Modify the edit templates to use the edit script service.

* Make the top level categories for Editor<XDOM> (i.e. PureText, Text and Wysiwyg) case insensitive for backward compatibility
* Add "PureText" editor as it is required by some TextArea properties (whose value is not wiki syntax)
* Set the "editor" meta property of some known TextArea properties (whose value is either code or plain text)
* Modify XWiki#getEditorPreference() to use the EditConfiguration component
* Deprecate XWikiContext#getEditorWysiwyg() which is not needed any more
* Modify TextAreaClass to use the EditorManager for displaying the right editor in edit mode
* Remove code duplicated between editors/xdom*.vm
* Remove textarea_text.vm and textarea_wysiwyg.vm as they are not needed any more

* Add an option to reset the default WYSIWYG editor
* Add translation keys for GWT editor's name and description

* Applied the same fix that was done for the Edit action for XWIKI-12392 on the deprecated Inline action (setting authors on the edited document, if it's a new document), to keep compatibility

* Improve the support for translating the editor name and description
* Move the code of a wiki-based editor from the document content to the "code" property and leave the document content for the editor description because the document content and title (= editor name) are translatable

[Misc] Fix javadoc. I need Thomas's help to document <E>, <F> and more generally to finish the javadoc for these classes.

* Add support for configuring the default WYSIWYG editor in the "Edit Mode Settings" administration section.

* Small improvement (thanks tmortagne)

* Register the wiki-based editor components automatically (those defined with XWiki.EditorClass)

- Fixing test
org.xwiki.test.webstandards.framework.DefaultValidationTest.Validating
HTML5 validity for: xwiki:Help\.SupportPanel.Content(fr) executed with
credentials Admin:admin (from org.xwiki.test.webstandards.AllTests)
- Caused because the committed version was from the l10n’s Application
Resource Package, which does not support Nested Spaces, since l10n is
on version XE 3.1

XWIKI-13543 : Documents containing single quotes in their name can't be rated in case of having separate space rating storage enabled

- new hint messages for description and icon fields
- moved translations to a new created translations page in the administration module

* Improve abstract class/method name.
