Jars are now all built in profiles:
* "library" builds the WDTK library jar (used to be default)
* "client" builds a standalone client jar
* "sign" builds the javadoc and source jars

The "library" jar does not include the client code, and in particular it
does not pull in the Log4J dependencies (!).
