Modified audiodevices example to list all supported formats

Divided the UI into two tabs:
- One which lists all formats supported by the device, in a table.
  This table is populated dynamically when the user presses a button,
  rather than at application startup - for some backends such as ALSA,
  isFormatSupported() is a time-consuming operation.
- One which allows the user to specify a particular format, and then
  test whether it is supported.  If the format is not supported, the
  nearest supported format is displayed.

Changing mode causes test result to be cleared.

Call showFullScreen() on small-screen devices.
