Spherical area lights example (#3498) I was putting together the Bevy 0.6 release blog post and wanted a simple area light radius example, so here we are :) ![image](https://user-images.githubusercontent.com/2694663/147786883-63454290-b5b1-4456-9762-0b0b47e16bb5.png)

default() shorthand (#4071) Adds a `default()` shorthand for `Default::default()` ... because life is too short to constantly type `Default::default()`. ```rust use bevy::prelude::*; #[derive(Default)] struct Foo { bar: usize, baz: usize, } // Normally you would do this: let foo = Foo { bar: 10, ..Default::default() }; // But now you can do this: let foo = Foo { bar: 10, ..default() }; ``` The examples have been adapted to use `..default()`. I've left internal crates as-is for now because they don't pull in the bevy prelude, and the ergonomics of each case should be considered individually.
