Create Javadoc jars when packagin releases

[GoogleCodeExporter]

Please create a guiceberry-X.X.X-javadoc.jar when packaging the release.  This 
will make it much easier for me to mirror it to the Maven repository where that 
jar is required.  Also, it is really helpful for Eclipse users since it will 
use that jar to give you the JavaDocs for a method you're calling within the 
IDE.

Also "ant javadoc" fails because you don't first create the directory 
build/dist/guiceberry-X.X.X

Another improvement, though minor, would be to have the sources jar that's 
generated be named with a -sources suffix instead of -src since that's required 
by Maven.
