There was a pre-existing jshint config (.jshintrc) file that this upgrades based
on the equivalent files for VisualEditor and OOjs UI.

This adds a TemplateData manager to the edit page in the Template
namespace.
If a <templatedata> tag already exists, the tool will parse it and
display it in a visual interface that the user can then manipulate in
their own language. If there is no <templatedata> tag, the dialog will
appear empty and allow users to add and tweak their desired template
parameter data.
The tool also allows rudimentary parameter import, which picks up the
parameters from a current template into the GUI to make the user's life
easier when producing TemplateData.
The template documentation editor feature is off by default. To enable it
use $wgTemplateDataUseGUI = true in LocalSettings.
