new Wa7kpk-20140823 branch

Hi Graham,

I notice that the hamradio gem hasn't been touched in a couple of years. In that time callbytxt.org has gone dark and the gem fails on callsign lookups.

I don't know if this is a branch you don't have time for, or what the situation is, but I wanted to propose a couple of changes to the gem to update the callsign provider to hamqth.com and in the process add a DXCC information function. Hopefully this looks useful to you, but if it's something you won't be able to accept, let me know.

Thanks & 73,
