This completes the migration of custom derives to proc-macros, removing the need for the `custom_derive` feature in consumer code. This commit also includes documentation, unit tests, and compile UI tests for each of the derives. Additionally, this commit improves the existing `FromForm` and `FromFormValue` derives. The generated code for `FromForm` now returns an error value indicating the error condition. The `FromFormValue` derive now accepts a `form` attribute on variants for specifying the exact value string to match against. Closes #590. Closes #670.
