Added friends_from_profile method which returns a list of one or more other profile's friends.
Updated login test script to work like the others, added tests for friend_from_profile method.
send_friend_request:
Applied patch from Olaf Alders to return human-readable status codes. Added his CAPTCHA-handling sample code to docs.
Message.pm:
send_all method now returns a response code (fixes a bug in message_group in which it would say "Stopped due to " instead of specifying why it had stopped).
approve_friends:
Added "-gc message" argument. If used, approve_friends, after approving and commenting new friend requests, will leave "message" as a comment for existing friends.
