- Fix extendsFrom.
- Add Category attribute (apparently it's better than Usage? Although there's no explanation for this gradle/gradle#27991 (comment))
- Experiment with filtering via artifact view... (but it doesn't work because Gradle sucks gradle/gradle#27991)
- Create Configurations rather than register them, because Configurations get eagerly created anyway.

(initially done to avoid `val name`'s getting clashing with `Named#getNamed()`, but the property is private so it doesn't have a getter so there's no clash)

…ame machine

…le managed type

(they're not used, but they're nice to have)

- Hide checksum type, and rename function so 'md5' isn't implied.
- Use SHA-256 (md5 vs sha256 doesn't really matter, but why not)
- Base64 encode (smaller log output)
