Port integration code to 6.x

hm, I've troubles applying the patch. please make sure to create it for the latest code in 5.x-dev. Please also check if one of the latest commits might be relevant for the 6.x port too: http://drupal.org/project/cvs/68360

As the rolesignup integration is gone, there shouldn't be many. Perhaps these are relevant?
#199298 patch by David Lesieur: Sort profile creation links according to nodeprofile weights
#199342 patch by David Lesieur: Allow theming of create link
#193603 patch by mh: Index themed nodeprofiles instead of rendered nodes. Useful for heavily themed node profiles.

ok, let's set this on hold until the discussion about joining profile node modules comes to a result.

I based the prototype on this work, but stripped out user edit categories and registration integration. That could go in another module "content profile integration" or so.

ok, for 6.x use content profile: http://drupal.org/project/content_profile

What's missing is the registration and user edit categories integration, which will go into an extension module.

yes, there won't be a nodeprofile 6.x.

as stated there, there is already an upgrade path as far content profile supports node profile features

As of now, both features are present in content profile! So I mark this issue as fixed.
