Scaffold a script that scans template changes

[decentral1se]

This should re-use existing solutions, approachs and best practices from actors like dbpedia and mediawiki itself (libraries and whatever is available for use in the FLOSS world). We're most interested in discovering when the template is edited. Other things will follow, but that is our first concern. If this script can understand when a template is changed, then we'd like to plugin in notifications of that into a trello (or whatever) through a 3rd-party API binding. We're aiming for very minimial and flexible glue here for the first step.
