show Chapter titles in Visual editor

Changed `html` method's internal `parse` variable to `parsed` to avoid collision with the shortcode `parse` method, which I use to get the title. Calling `parse` on the shortcode data seems a little redundant, considering `html` runs a couple expressions on it already, but I'm not aware of the reasoning for some of the conditions in there, so I didn't want to oversimplify anything.

Also added uglify task for tinymce plugins.

There might be some other components that would benefit from showing a little bit more data in the visual editor, but I'll leave that up to you!

Also, apologies if I botched the `sourceMap`.
