Release 0.10.0

The first version filled its widget with the figures, which the owner found
huge. The figures are now measured against the icons: small is half an icon
tall, medium (the default) most of an icon, large taller than an icon, with the
widget's own height and width as the limit.

The owner chooses left, center or right and the size from the widget's edit
button. The options are a sheet over the home screen, kept per widget, and each
choice shows on the widget at once.
