Adds the Apache Felix Bundle plugin to the pom file which will generate the appropriate OSGi headers.
Change the packaging type from 'jar' to 'bundle' to enable the bundle plugin to join the build. 'bundle' is the same process as 'jar' with the extra step of scanning the classes and generating the OSGi headers into META-INF/MANIFEST.MF.
The only difference between 'bundle' and 'jar' are the extra headers in the manifest.
