Avoid gitolite-admin test if conf has a parent
goglt: update usersToRepos with subconfs
gitolite_test.go: uses NewGitolite(nil) instead of NewGitolite()
Make UserOrGroup public, add rule.GetUsersFirstOrGroups()
Test parent gitolite and undefined group
goglt uses rule.GetUsersFirstOrGroups() instead of GetUsers()
goglt prints a group as a system account, not a user one
Rename goglt.go to gogtl.go
[gocyclo] reduce cyclo complexity of gitolite.addGroupRepoToConfig()
