Send contacts in the layout N1MM actually reads

Browse Source 
QsoRecord followed MultiOpManager.QSOString, a helper N1MM does not use
for the network. The messages use Contact.QSOString: 43 fields, the
continent before the contact type, and flags as numbers. N1MM converts
the multiplier flags with ToShort and threw on 'True', so every contact
logged here raised an error at the other computer.

The id now goes out as a GUID and is kept on arrival, which is what the
other station's checksum of a resync block is made over.
