(svn r7505) -Feature: show NewGRFs used on a game server, show which NewGRFs you do and do not have.

Browse Source 
-Feature: show NewGRF compatability of network games in the Game List window; a green square if you got the same OpenTTD version and have the needed NewGRF, a red square if the version does not match and a yellow square if the version matches, but the client is missing at least one of the NewGRFs.
