Callbacks
---------
core.button_handler(fields): called when a button is pressed.
^ fields = {name1 = value1, name2 = value2, ...}

^ event: "MenuQuit", "KeyEnter", "ExitButton" or "EditBoxEnter"

Gamedata
--------
The "gamedata" table is read when calling core.start(). It should contain:
{
playername = <name>,
password = <password>,
address = <IP/address>,
port = <port>,
selected_world = <index>, -- 0 for client mode
singleplayer = <true/false>,
