[CQ-Contest] authentication for log submission

[W0MU Mike Fatchett]

I think LOTW went a bit far.  I don't need to jump through all those 
hoops to trade stocks or check my bank accounts etc.  Most browsers have 
security built in with encryption.  This could be used.

I wonder how many people refuse to use LOTW because of the difficulties 
getting going?  We certainly do not want to get to point where people 
will not submit scores because a system is too difficult or restrictive 
to use.
