All macro validations now return spanned darling::Error instances. This produces compile-time errors in the right places in input source code.

Largely fixes #7, though unwrap() calls can still cause the macro to fail.

PR Notes

Testing of the errors was done by deliberately breaking arbitrary_self.rs, but those changes weren't committed. It's possible to do compile-error tests for proc-macro crates, but it's not easy.
SelfType got some new methods to reduce boilerplate in other files.

oh wow, thanks a lot for this, it looks great!

As long as all the current tests pass I am happy with this without adding tests that verify the compiler error messages.

Thanks!
