[GUI Server] Save list of last IPs / address

[Yona-TYT]

Currently you always have to type the IP or address to be able to connect manually to a server.

Can you create a list of the last addresses entered? Something like a selector or drop-down filter where the entered addresses are saved so you don't have to type them again the next time you open simutrans.

Yes, I have been copying and pasting, but since I was testing with the chat, I lost count of the number of times I copied and pasted the IP, so a list showing the last IPs used would make our lives easier.
