Completed Story "Put HTML into a Content Widget"
Implemented STI subclassing where ContentWidget subclasses Widget
Hooked up lots of view logic

Notes:
Does not integrate with user authentication
For it to make sense, you need to create a WidgetTemplate called Content Widget of class "ContentWidget". This will be solved next with the seed process.
