Add EventWriter (#1575) This adds a `EventWriter<T>` `SystemParam` that is just a thin wrapper around `ResMut<Events<T>>`. This is primarily to have API symmetry between the reader and writer, and has the added benefit of easily improving the API later with no breaking changes. 2021-03-07 20:42:04 +00:00			`use bevy_app::{AppExit, EventReader, EventWriter};`
