Improve the way messages with compound calls are automatically generated. 

Routine packmsg now tries the shortlist (Type 1 prefix or suffix) first.
Then it tries to to make a valid message using a Type 2 prefix or suffix.
If both fail, it packs the first 13 characters as a free-text message.

The GUI now generates the most useful messages with compound callsigns
of all valid types.
