XWIKI-10389: The Blog title is hardcoded in English

This is good but note that it makes even more urgent for us to find a solution so that end users can understand this field value. They used to see "The Wiki Blog" and they understood they could change it. Now they see "$services.localization.render('xe.blog.code.title')" and are now hesitating to change it since it looks complex and they fear breaking something ;)

This is a generic issue we have in lots of places. Maybe we need a specific "light WYSIWYG editor" when editing String properties so that the user sees the rendered value when editing it.

Something for the list I guess... :)
