Make sure that aliases get trimmed and are not getting extra spaces
when saving a parameter.
NOTE: To prevent dirty diffs, only parameters that are 'touched'
(viewed or edited directly in the editor) will be trimmed. The editor
will keep all other "wrong" values that have trailing or preceding
whitespaces as-is.

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.
