Treat select types as opaque on model generation.

Added option to treat certain types as opaque and not generate models for.
Currently it defaults to java.util.UUID & org.joda.time.DateTime, other types can be added via the
typesToTreatAsOpaque option (it's a list).
readme updated for 0.0.2
javadoc plugin to 2.9.1
swagger ui to 2.0.0
Sometimes getResourcePath() would return null which caused a NullPointerException
Change example dependency to 0.0.3-SNAPSHOT

0.0.2-SNAPSHOT gives a 404 on OSS Sonatype.
Update dropwizard sample version in example

It's building v0.0.3-SNAPSHOT, not v0.0.2-SNAPSHOT
