Subject: altosui: switch channel selector to combo box. Shorten displayed
 device names

A combo box displays the current value, which is quite nice to
have. Add a 'toShortString' for AltosDevice so that the window frames
and error messages don't have extra spaces generated by the
altos_device toString method.
