[Dx4win] LOTW Support

[Kostas SV1DPI]

I agree that dx4win needs update urgently, especially with its LotW 
features.
Easy upload to LotW (integration with TQSL), DXCC submission giving 
priority either LotW or cards and having in mind all the new things ARRL 
asks, as auto connection in DX clusters is a must.
The most important reason for someone to remain in Dx4win is its' 
database (tnx Jim AD1C). Because the most important feature for a 
logging program is to keep my qsos safe (and this works 100%) and the 
second one to tell me right what DXCC entity is every call. So i remain 
here as long as Jim is also here!!!
