Add new config options:
git-p4.detectCopies - Enable copy detection.
git-p4.detectCopiesHarder - Find copies harder.
The detectCopies option should be set to a true/false value.
The detectCopiesHarder option should be set to true/false value.
P4Submit can now process diff-tree C status and integrate files accordingly.
