Provide simple way for administrators to send users a new password

There are situations when, as an admin, I would like to send a certain user a new email. For instance, if I had to manually modify their email address, I might as well send them the new password so they can log in.

As far as I can see, it is not easy to do this at the moment. Basically you have to log out, go to user/password, and enter their name or email. Then log back in... The reason is that access to user/password is restricted by $user->uid == 0. I don't see a reason why admins should not would have access to that page, which would at least make it possible to reset the password without loging out. So I propose to change the access to '$admin_access || $user->uid == 0'.

Even with that change, it is slightly impractical to send the password just after you changed the email (for instance). I wrote a small patch that adds a "reset password" to the user view of admins. Then you can do it with just one click. I can submit my patch if it is agreed that it's useful, or I could adapt it to suggestions, just let me know.
