Membership 2.0.4

Hi gang

Membership version 2.0.4 is now up and ready to grab.

Main updates in this version are:
- fix for marketpress pages issue
- new marketpress pages rule
- fix for the negative page restrictions rule
- fixes for some bugs found within the communications module (namely the extending of variables)

Moved the admin rules to become an add-on so they can be removed if not needed / wanted
Moved the plugin repair facility to an add-on so it can be removed if you are sure that you installation is ok

- fixes for some customisation / form overriding functions so the signup and subscription forms can be completely altered.

It's available from the usual place.
