Remember position and size of the window

[McGiverGim]

Fixes #377

Remembers the window size and position. At least for the first window. If you open more than one only the first is respected. I think is enough.

One concern that I have is that this will obviously lead to ever-increasing metadata for the app, as every time a new window is opened a new entry for its id is created. But I think this is pretty much cosmetical.

[McGiverGim]

I suppose you are talking about when creating "others" windows. This change will add a constant id for the main window, but when opening more than one I suppose that yes, this others will create a random id.
Do you know where this metadata is stored?

[mikeller]

Wait, I'd misread that. Been a long day ;-)

[McGiverGim]

Not at all. I think your concerns have sense when opening more than one window. If I have time I will do some tests to see the behavior but it will be for another PR.
