Users requesting access to groups/projects should generate todo's
Description
Currently, when a user requests access to a project or group, emails are the only things sent out noting this to the correct people. Not everybody wants emails for such requests, they'd rather that normal todo's are used instead.
In fact, many other actions a user can take that requires attention from higher ranked people all generate todo's for the affected people, so why doesn't access requests?
Proposal
When a user requests access to a group or project, todo's are posted to the people who can grant or deny the request.
This does not mean emails should be removed, just that adding todo entries would be appreciated.
