[1.7.0] Implement HTMLDefinition cache (very hacked together, but long unit test times were driving me crazy!)

- Add extra protection in AttrDef_URI against phantom Schemes
- Doctype moved from config to HTMLDefinition
- AttrDef_URITest mocks have more generic object parameters to deal with PHP4's copy-happy behavior
