Mention where the files land if you pick the "app" permission

I've just configured Dropbox-Uploader and uploaded a file to a specific path:

    dropbox_uploader.sh upload QS_Forum_backup_2014-07-16T20-00.zip "QS Forum Backups/QS_Forum_backup_2014-07-16T20-00.zip"

However, the file landed in `/Apps/QSForum Uploader` (the name of the app I created), and only under that in the `QS Forum Backups` subdir.
