Show player picture left of device configuration.

After shrinking the size of the Rockbox logo shown and making the selected
device display two lines there is now enough room to also show an icon of the
player. The icon is scaled depending on the application font size, so for
setups configured with a larger font it still should show up in a reasonable
size.
