redhen 7.x-1.0-alpha2

Loads of bug fixes and improvements. Note that RedHen Membership has been extracted into its own project and removed from RedHen core. This was done since it's not needed for all RedHen use cases and removes lots of complex code from RedHen core improving stability.

• Using new redhen_connection constant.
• Using new redhen_affiliation constant.
