Url strictness

[samuelcolvin]

Continuation from #317.

turns out I was a bit hasty when merging URLs.

We need to support multiple hosts, but while thinking about that, I realised we should use SyntaxViolations in strict mode.

Still to do on this PR:

• add a passed_strict flag to Url and check it during validation in strict mode
• new UrlType error if Url type checks fail
