Add support for remembering settings

Use QSettings to provide persistent storage of settings. For example, we
store and restore the size of the MainWindow.

We use the organisation name hohndel.org and keep subsurface as the
application name.

A section is specified for things to do with the MainWindow; other
sections could be added e.g. for preferred units?
