Fix some comments after the move of files to jaggr-core from jaggr-service.

@chuckdumont Not sure what happened with the merge of the previous .properties fix to the pom, but it looks like my commit I sent to you in a pull request got re-written or something.  Anyway, git wants to merge what's left of the commit in my branch back to master...  so that's the 1st change listed here.

The rest are comment updates and 2 instances of a removal of OSGi dependencies that were only referenced in the javadoc.
