gitlab/lib/api/projects.rb only changed the lines mentioning namespace_id. these were added to allow project creation within namespace (from API). If not used, it defaults to your username. This allows gh2gl to work "git clone http://code.a8.lc/administr8/github2gitlab.git" for github to gitlab migrations.
