gdk::EventButton is missing a "get_button()" function

[Nathan]

You can do event.as_ref().button but a convenience method would be nice

Feel free to add PR.
Minor variant just add function to https://github.com/gtk-rs/gdk/blob/master/src/event_button.rs#L13-L27.
Better: create rusted enum on https://github.com/gtk-rs/sys/blob/master/gdk-sys/src/lib.rs#L697-L699 using https://github.com/gtk-rs/gdk/blob/master/src/auto/enums.rs as example.

I don't trust the docs saying the button range is 1-5, an enum likely isn't appropriate.

Seems this can be closed
