Download (and upload) avatar images from mattermost and telegram when mediaserver is configured. Closes #362
An extra avatarMap (cache) is created for mattermost and telegram. If MediaServerUpload is configured, the avatar images of users are downloaded the first time a user sends a message. If this download succeeds a message with EVENT_AVATAR_DOWNLOAD is sent to the originating protocol. This message also contains a SHA field (in msg.Extra["file"]), if this is not empty, the sha will be added to the avatarMap. (so we now have a userid-sha cache) Next time this user sends a message, the MediaServerUpload/sha/userid.png URL will be used as the avatar field.
