(This is the first commit done via the new DevTest environment)

cisco-rev-sync updates
*  The main purpose with this commit was to enable timestamp-logging of this script (to be the same as rest of our sync-scripts), so that it logs to the same file as the others.
*  Also started adding devtest-capability (cmd-line arguments, variable paths)
*  Did a little bit of cleanup and refactoring
*  Tested, and at this time, was able to run it manually so that it always creates new cisco-rev cdets, but not do anything about syncing/updating already-existing ones.
