* Add SyntaxContent editors.
* Configure the default SyntaxContent editor in the "Edit Mode Settings" administration section, instead of XDOM editor
* Use the SyntaxContent editors in the edit templates (for page content) and for TextArea properties
* Modify XWiki#getEditorPreference() to return the prefered SyntaxContent editor (instead of XDOM)
* modify templates/editors/xdom*.vm template to support SyntaxContent input
* Make sure the leading white-space is not trimmed when editing in Wiki mode

XWIKI-13551: Instance Output filter should use current locale as default locale instead of Locale.ROOT

* Use the PureText editor for TextArea properties that don't contain wiki syntax.

* Fix webstandards validation tests (the code from ConfigurableClassMacros was wrongly assuming that the value of the id/for attribute is always wrapped in apostrophes)

XWIKI-13528: Add support for replacing the default WYSIWYG editor

* Use HQL instead of XWQL because the later requires the class definition to be present in order to determine which column to join.

* We cannot overwrite the existing bindings in the Velocity context when copying script context bindings because we have Velocity scripts that expect $doc instance to be shared among them.

This reverts commit 9e5dadc4.

XWIKI-13551: Instance Output filter should use current locale as default locale instead of Locale.ROOT

* 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)
