v0.8.0

The next major release of Serenity, coupled with improvements, bugfixes and some breaking changes.

group! is now #[group]

To stay consistent with the #[command], #[help] and #[check] macros,
the function-like group! procedural macro has also joined in to
the squad of the attribute procedural macros.
