macOS: When closing the last main window via x button, remember opened repositories.

In macOS, when quitting SmartGit and then relaunching it, it remembers the last open repositories.

But this is not the case when closing the last SmartGit main window with the window's x button, and then relaunching it -

It doesn't remember the opened repositories, and just opens with all repositories closed.

This is very annoying!

I hope you can fix that.
