Add forum role when adding new/existing users

[johnjamesjacoby]

When adding or inviting a user to a site, it would be nice to include the bbPress forum along with the site/blog one. With actions introduced back in WordPress 3.7, this is now possible (it wasn't the last time I looked, yikes.)

In 6675:

Users: first pass at forum role selection on invite/add-new.

This change adds the ability to set a specific forum role when adding a new user. If no valid role is found or saved, the default role will be used by default. There is likely more to do here, to ensure auto-role continues to work as intended as well.

Trunk, for 2.6. See: #3157.

Form field added (single site)

OK. I think this is working as intended.

It might need more testing with weirder multisite setups, or with BuddyPress on single-site and a custom WP Signups table, but we can work on those integrations later if something comes up.

A number of improvements are necessary to this feature, so this issue is being reopened to track commits in the current milestone.
