jSDP 1.1 released

Today the version 1.1 of jSDP has been released.

It's mainly a bugfix release, because previous versions of jSDP cannot handle attribute fields with the same name (thanks to Peter Hanecak).

Moreover I changed the classes used for store message fields: Hashtables and Vectors are no longer in use.

Obviously also Maven 2 repository has been updated, and I plan to submit jSDP artifacts (at least the latest version) to Maven Central Repository.
