WP Roles & Capabilities - BP integration

[DJPaul]

BP is currently lacking any use of the WP roles and capabilities system, apart from is_site_admin(). It would be nice to encapsulate some of the current is_site_admin() calls with a capability check. It can be built on going forward.

For example, you could add a capability to your WP Editors role to let them become "site group moderators" -- as in, BP Moderators of every group without having to be a member of the group.
The downside of being able to moderate every group in the current system requires you to be a member, which fills your own Activity Stream with lots of noise.

I've attached a very early patch showing the sorts of changes I'm thinking of and encourage feedback.

Sorry, the .patch version has syntax highlighting :)

WordPress 3.0 has meta_caps. I recommend you look into using meta_caps instead of the route you have proposed here. Adding roles can get messy in a BP_ENABLE_MULTIBLOG install.

wpmuguru, do you have any documentation on meta_caps? I can't find much. Thanks.

Oven is on.

Probably should aim to do this in 1.7, when we've a better plan for how/if/what/where post types may affect this.

See #3740 for further discussion.
