Fix "Failed settings permissions for File" (os.chmod(dest, Env.getPermission('file')))
Before this fix, couchpotato never apply permissions when file owner != launch user of couchpotato.
Now even if file is created with other user (sabnzbd, transmission...), the owner is changed to couchpotato user (eg. couchpotato), and os.chmod can apply the permissions defined in settings
Because launching all service with the same user is not the solution (just hacky and insecure)

Nothing is impossible
