[RTTY] Trailing CQ

[Alex, VE3NEA]

The latest version of RTTY Skimmer Server (not yet published, will be tested by a few volunteers in the EA contest) discards the 
CQ if it appears between two different callsigns. This should eliminate one scenario of invalid spot generation (<runner> CQ ... 
<caller>), or at least reduce its frequency - if the first call is lost to QSB, the second one may be spotted as running. There 
are several other improvements to the CQ/DE detection algorithm, they all need to be tested.

I am adding code to ignore CQ in the "CQ. <call>" combination, as you suggested, those who want to experiment can put "CQ." at 
the end of the message and see if this helps.
