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.
