Fix at #161

The base widget class shouldn't have been in the list, which is one of the issues here. This was due to the class name in the array key being lowercase where the code expects standard class names.

This does "fix" it, however adding a widget to a page and saving it redirects to a 404 for some reason. Refreshing the page shows the widget is still created. I'll look at this separately.
