Macro make_multi_input

    ($multi_input:ident, $multi_scheme:ident, $( ( $( ($A:expr, $I:expr) $(,)? ),* ) ),*    ) => { ... };
}

Eases the setup process for binding keys for multiplayer. The first argument is a MultiInput object, the second is a MultiScheme object, and the remaining objects are tuples containing one or more tuples of type (A: Into<Action>, I: Into<UniversalInput>).
