Add option to set IP address for devices

[kai11]

I'm using syncthing server whihc available from wifi network only.
Global and local discovery, relays are disabled.
I can add this device to syncthing with static address (e.g. tcp://192.168.1.2:8435) and it works, but I cannot add it to syncthing lite because it cannot discover it.
Please add dialog where I can add device with static non-discoverable address.

I have the same problem because I do not connect to the relays servers.
Great job. Congratulations
