Having to manually request the list, with two buttons (get new
list, refresh list) is somewhat confusing. Also since it looks
like there are no servers, users might not try to figure out
how to get the server list.
The first time viewing a master server list in Team Arena UI,
automatically request a new server list. After that the cache
will be available with a timestamp of the last refresh time.
I think this will make it easier to understand how the menu
works.
This may cause unneeded updating of the server cache because the
last refresh timestamp is per-fs_game but the server cache is
shared by all games. This will only occur once for each game
though so it's not a big concern.
