Save window size/position

[awgrover]

It would be very nice if antimony remembered the window size(s) and position(s). I always have to move and size them to take advantage of my screen.

The size/position probably should NOT be in the .sb. Imagine sharing a file, or putting it in source-control.

Probably, the size/position goes in the user's antimony directory (e.g. ~/.local/share/antimony on linux). Or, should it make a file next to the .sb (kind of like vi's .swp fles)?

If the size/position doesn't fit on the screen, use the app's default.

The app should have a preference for size/position. I arrange my windows everytime when I start a new file.

I looked through the code at one point to try to figure out how to do this, but couldn't track all the pieces down.
