`SelectionList.select` doesn't post `SelectionToggled` message

[TomJGooding]

Alright, now I know where I went wrong: When looking into textual's code again I found out that SelectionList.toggle triggers the event while SelectionList.select does not. I only tried out SelectionList.select before :(

Looking at this now.

Spotted a couple of issues relating to the messages in SelectionList, so going to do a pass over it and try to make sure it's posting the right stuff from the various different methods it offers.

I actually believe this is just some lacking documentation.

The semantics of toggle is just that it was explicitly toggled i.e. using the keyboard or a toggle call. The original poster is just handling the wrong event.

I've made the semantics clearer inside docstrings (and also ensured that Toggled messages are sent when toggle_all is used).
