Capabilities/mod/forum:initialsubscriptions

• This allows a user to be subscribed initially to forums
• This capability is allowed for default teacher, non-editing teacher and student roles
• This capability is not set for default admin and course creator roles so they don't receive unwanted forum subscription emails. If this is set for any role that is used at system level (e.g. admin, course creators), assigning users to these roles will take a long time because users will be subscribed in forums in all courses.
