Special users (like admin) sometimes do not have family and given names. With this fix these fields will be ignored if the user already exits and they do not have them. New users are created with these fields.

Added automatic pagination of the results from the CF API. Methods return all the resources.

• Method cf.request now is public in order to make use of the URL responses in CF API

• Added UAA user/group/client management
• Added CF user management with roles for orgs and spaces

First functional version
