fix location bug

[hx2A]

By default, the thonny plugin will open a new window to the location 50,50, which is in the upper left corner of a one monitor setup. If the user moves the window to a new location, the plugin will remember the new location and open the next window to that location.

This works just fine for most people but not me. I have two monitors of different sizes, and it happens they are arranged in a way so that 50,50 is not visible on any monitor. Therefore, by default the window will open to an invisible location. This is very frustrating, it makes the plugin unusable on this machine.

I updated the code so that now if there is no previous stored location from a previous Sketch, it will default to the center of one of your displays. It will not put the window some place where you cannot see it.

Hurray!
I think might fix #44
I had this issue in class a few times and it is very frustrating.

To be extra cautious, the plug-in should forget about window location on Thonny restart, I'm not sure this is already the case.

Yes, this should fix that problem. I believe it will forget the location on a restart but you should double check that.

I believe it will forget the location on a restart but you should double check that.

For the record, I tested on Windows and it does not forget the window position. But maybe it's not a problem anymore, because it defaults to a sensible place... we'll see...

Hmmm, this must be a Windows thing.

Does it get tripped up if you disconnect a monitor? If the Sketch window was last positioned on a screen that is now disconnected, sometimes that causes problems.
