[PATCH v2 1/2] git-p4: Improve rename detection support

From

Only open files for edit after integrating if the SHA1 of source and destination differ from each other. Add git config option detectRenames to allow permanent rename detection. This options should be set to a true/false value. Rename "detectRename" variable to "detectRenames" to make it more coherent with the description in git man pages, which always use plural.
