Merge pull request #785 from jdgarrett/statistics-fix

Fixed some issues with the authors in the statistics web op.
Reverted gzip compression for some remote requests.

The compression was causing an issue in some cases such as
cloning from the mac command line, or geoserver to geoserver
repo communication.  Commenting it out so that geogit remains
functional in those cases.
Make HttpRemoteRepo.pushNewData use the same logic than LocalRemoteRepo to set the remote ref name to be updated
remove GPL mention for the geoserver plugin as its not part of this codebase anymore
