Add a handler for plain python files that starts the python idle displaying the file.

It looks awesome! My thoughts for this issue were to allow opening the IDLE that comes with Python.

Adding a full fledged editor feels a bit out of scope for the interpreter, but I would love to do some integration where you have the possibility to edit the file in your app and run it with the PythonHost (see #8). This should already be possible to some extend, if you start an indent exposing the .py file. (see #3)
