find_rtkbase reliability

[Jef239]

Before making these two changes, find_rtlbase was unstable for me. It would show between 6 and 9 stations (there are actually 9).

Also, sorting by name improves usability. Our clients sometimes have up to 50 stations in a single VPN network.

I only saw crashes when accessing by service name. It seems mDNS isn't working very reliably. However, I didn't see any crashes when accessing via IP. Therefore, I tried first using IP twice, then using the server name.

And accessing via IP significantly reduced the search time.
