Fixed an issue where Flannel would throw errors when a directory
already existed and it tried to git clone the repo.  These errors
created problems for CI automation systems like Jenkins and
Travis, which parse console output to determine if a build failed
Fixed a typo that was causing the error message 'Either plugin or theme must be set to True.' to appear erroneously
