XWIKI-11602: Introduce a configuration to select the HTML version to use according to the current skin.

 * Typo + minor improvement.
 * Note that one improvement would be to offer a getLastError() API as we do in other script services (we do need something generic for all Script Services for this btw)

- Using the rendering script service instead

- Moved the code and tests to platform.

[Misc] Fix the jacoco error in the top level POM so that we don't have to copy the configuration in lots of modules and so that it can be fixed in one place, when it's fixed upstream.

[Misc] Convert test to Mockito + add some unit tests + really make it a unit test (and not an integration test)

* Fix test that requires the WYSIWYG editor to be present and configured

* Bug provoked by a bad character.

[Misc] Remove unused parameter + fix exception message + add missing deprecated annotations. Thanks to Eduard Moraru.

- Added syntax ID parameter when using the XWiki syntax escape tool

* Use String#strip() from Prototype.js because IE8 doesn't support String#trim(). Prototype.js uses trim() under the hood if it's available.

* An element that has been removed from the document may still have a parent and some sibling nodes in IE8 ...

* revert modification made by mistake

* fix checkstyle

* move translation in the right place

- save as minor edit
- provide a message when saving the rating document

undo the type name change and add a comment

* Added ability to specify technical pages too

- Used syntax 2.1 path: links.

* so much for writing unit tests
