FIX: replication should work now (wrongly created upstream definition + replace BackendStat code)
Merge pull request #84 from reneme/fix_replica

FIX: Replication of Repositories



This failed because of two things:

    cvmfs_server add-replica generated a misconfigured upstream string
    BackendStat was dead code that needed to be replaced but wasn't yet.

Note:
The temporary directory (download location for replicated files) might not work with Riak at the moment. This is kind of tailored for local backends in cvmfs_server add-replica/snapshot and might be replaced by a flexible C++ implementation to take different backends (with possibly different replication techniques) into account.
