    allow digits in scheme regex
    discard old supported-schemes code
* UURIFactoryTest.java
    tests for roundtrip serialization of problematic hostlike-scheme and bars-in-path
* CrawlerLoggerModule.java
    discard special-casing of URI scheme errors
* SchemeNotInSetDecideRule.java
    rule to apply to URIs of unknown schemes; by default REJECTs those not usually handled by Heritrix
* **/profile-crawler-beans.cxml
