Keybinder

Wraps Keybinder in a safe way

Example

```rust use keybinder::KeyBinder;

fn main() { gtk::init().expect("Failed to init GTK"); let data = String::from("some data"); let mut keybinder = KeyBinder::::new(true).expect("Keybinder is not supported");

assert_eq!(keybinder.bind("<Shift>space", |key, data| {
    println!("key: {} , data: {}", key, data);
    gtk::main_quit();
}, data), true);
println!("Successfully bound keystring to handler");
gtk::main();

} ```
