Create QSO::completeWith(const QSO & q2)

[ea4k]

The qso should read all the values of the argument q2 and complete if the calling qso has empty values.
If the calling qso has a value in a variable and q2 too, q2 value is never overwriting the value of the calling qso.

Note: This will be valuable for import and lotw ... when a qso is duplicated
