Updates to user_permissions_template_generator.rb that includes a column allowing one to specify one of:
A) An existing Rally UserID to provide the template/source of permissions for the new user
or
B) Viewer/Editor as default rights throughout the project hierarchy.

Also: bug-fix for user_permissions_loader.rb fixing crash when a Workspace Administrator without create user rights tries to update permissions on users not already present in Rally.
