Set viewBox to "2 2 20 20" to trim 2px off each side of our
existing 24px icons, therefore aligning them to the new 20px
grid. All of them had been drawn with large margins, so none
of the graphic is lost.

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.
