Bugfix: GitInputFormat illegally called listFiles,
must be listStatus.

Also: add a test for it.

Also: special case a file called "index" 
in GitInputFormat, since that's in the data set, 
and should really be removed, but that'd take a day.

Also: Remove HBaseDependencyJar, as it makes runs unreliable.
Add Main class to the clone detector.

Issues the job to the cluster.

Also: disabling GitInputFormatTest from automatic
execution, for the moment.

Also: JavaModule should be configured only once
in CCModule.

Also: remove offline mappers from cc pipeline.
It's easier to execute manually when all is done.

Also: I need TableAdmin methods in the clone detector,
even though those APIs aren't quite ready yet.
