VK1ET : --Interactive display changes

Browse source 
Based on a submission by VK1ET, but I've tweaked it a bit to use the
bFlags.

Basically, only print out values in --interactive that have been
received from the aircraft. Previous versions would display 0.000 for
lat and long for any positionless aircraft. This version prints blanks
instead for any/all fields that are not yet known.
