Set to 38400,8,N,1 just need to map the baud rate enums now.

qextserial library is no longer maintained, suggest we move
to this library, also greater chance for thread safety,
library now builds in cmake, will add Serial2 sources to
handle the new qserial, should easily plug into serial interface
now.

Fixed a bug where it was possible to "write" a waypoint list without any "current" waypoint. Now the last waypoint is set as "current" in this case.

Added proper support for fullscreen mode, fixed issue with window state update on perspective change

Removed SLUGS' PID form to give way to the parameter interface. Replaced Old SLUGS messages for their common equivalents. Hunting bug in Home Position in MapControl
