[IronPython] Stop script execution/unload script

Your intuition that you're running a kind of script that can be stopped is
leading you astray. :)
When you program in IronPython, it's very much like programming in C# -- the
objects you create will stay alive until they are garbage collected or the
program ends. So to unhook the delegate from the event, you need to do the
same thing from IronPython that you would have done from C#:
Button1.Click -= hello.
I believe that Runtime.Shutdown() will call any "atexit" methods you defined
from Python, so you can use this to perform cleanup.
