[FR] support more widget types

[ildar]

If the app/widget is going to develop it's worth thinking on adding new types of widgets. Some players devs don't pay attention to their widget's usability aspects. This is where TeaCup come in.

Thanks for the feedback. I currently do not have time to focus serious development effort on adding new features to TeaCup. I am happy to accept pull requests however!
