Fix ContextRoutingHandler.

Trust the defaults, I guess.
Fix the location of some dw-jetty tests.

THANKS REFACTORING.
Add support for security handlers.
Add level parameter for logging bootstrap.
Extract gzip and request logs to factories.

Also, move away from annotated fields.
Clean up ServerConfiguration.
Merge LoggingConfiguration and -Factory.

Also, rename LoggingOutput to AppenderFactory and change the property name to appenders. That's what everyone's expecting.
