New lobby server

Thanks to our friends at selfkill.com we have a new european lobby server. It is an additional server that you can use or not. Once you add it, the game will automaticly detect the faster server and use it. The new server is currently working independently so the servers on them are different than on the main lobby but they should be synchronized soon, when they're fixed.

Current list
Instructions:
- open lobby_servers.txt and below 'lobby.soldat.pl' place 'selfkill.com'
- or you can download this file (save as...) lobby_servers.txt and place it in the Soldat directory.
