UberSDR registers on sdr-list.xyz

[Bas ON5HB]

I just got word from Nathan, that Ubersdr registers automatically at sdr-list.xyz and it seems it's done from the uber-instance-list.

So we do not have to configure anything.

All Ubers online are registered. Not sure if need to say yes/no in the config, mine is set yes.

Hope to get more info later.
