Merge branch 'master' of git://github.com/castlabs/jclouds
* 'master' of git://github.com/castlabs/jclouds: added test for range requests with filesystem backend and corrected behavior Improve Range handling. * allowing to GET last n bytes. * start from GET range now spec conform (to field empty instead of Long.MAX_VALUE)
