Removed log4j. Added logging to slf4j (API only, no impl). Standlone logs directly to stdout and stderr. Prettified standalone startup output.
Merged Rob's changes
Refactor to move Jetty 6 specific code (fault injection, browser proxy request detection) under the jetty6 package (renamed from jetty). Also some renaming of existing Jetty-specific classes to Jetty6*
Added matching on URL path and query parameters
Added an additional query param test. Documented query parameter and URL path matching.
Merge branch 'master' into jetty9
