Setup Network window "All Networks" unclear in purpose, rename "New Network…"?

Test case

Steps

1. Connect to core
2. Open a ircs://irc.example.net/#quassel-test link

Expected

Network list shows New Network…, Create network…, or something to that effect, to indicate it's creating a new network.

Actual

All Networks is shown, without it being clear what will happen. Joining the channel on every network? Adding the IRC server to every network?

(I haven't yet tried this on a scratch core.)
