* Previously the meta-data was applied to the crate, which doesn't seem
to work.
* attempted to make `examples/auth.rs` work on stable. This isn't
properly tested now, as tests don't compile.
We are now at a state were stable as well as nightly work similarly,
but fail because `include!` doesn't behave correctly if macros are
involved. Namely it happens before crates are linked, yet it will
try to expand macros right away, which is a problem.
If the macro is defined in an empty fashion, it will actually be used
at include time, and expanded. Which causes issues further down the
compilation.
With the current 'fix' we manage to at least make everything but
`cargo test` work.

* Do not return massive custom result enums, but instead adhere to the
`Result` convention. This natively fixed our problem related to having
to make unnecessary clones, making our design much cleaner.
