Updated jssc to be compatible with maven and osgi.

I've updated and changed some packages. Also I've created a pom.xml which will compile jssc to a maven compatible osgi loadable version. I've changed the version tag in the pom.xml to "2.8.1".

Still missing is a custom loader for native libraries. At the moment  they must be copied "around" which I'dont like. It will be better if the classloader would be able to extract the libraries from the .jar file and use them.

Also a pom.xml which will build the natives is still missing.
