Change the ui/data behavior to work with oojs and event emitters,
and replace the gui from jquery ui to oojs-ui.
Changes made:
* Recreate the templatedata editor with oojs and ooui.
* Create a standalone templatedata model with internal validation.
* Allow the user to insert language-specific strings:
* Allow adding arbitrary languages and values
* Normalize output between language object and 'simple' string
* Add new language code by searching for its name or code
* Import parameters from template code
* If the template is in subpage and there is no code in the
current page, the code will request the contents of the parent
page.
