The vanilla main menu is an awful pile of code that is extremely painful
to make additions to. So I've side-stepped the problem by writing an
entiely new menu system without all of vanilla's quirks. I've separated
the custom menu system from the menus I want to make, which allows for
easy additions and a clear separation of responsibilities.
Along with this rewrite comes a host menu, adding the missing
configuration options in-game.
Fixes#29
Saves and loads last join IP/port attempt
Made host's port configurable in config file
Made host's save slot configurable in config file
Made host's player interaction setting configurable in config file
Indicated when the client was trying to connect on the join menu.
Fixed join menu display error where the port would disappear
