[pr 2702] finishing the `@StandardException` feature.

* rewritten how it works a bit: Now compatible with parent exceptions that don't have the Throwable variants.
* rewritten how it works a bit: You can now provide the full constructor only; the rest will forward to it.
* fixing up style.
* rewrite the docs.
