Remove 'Attach Files to User Profile' From Permissions Pages

From our documentation, it seems like the 'Attach Files to User Profile' permission is no longer relevant and as far as I can tell does nothing in the application itself. With that in mind, it should be removed.

Summary of the permission from our documentation
Overview of the global permissions

This allows the user to upload files to be stored in their user profile.

This feature was made obsolete by the introduction of personal spaces in Confluence 2.2. Hence, this permission is no longer relevant. Attachments can be accessed from a user profile view (for example, an image within the 'About Me' field of a profile view) by attaching these files to a page within that user's personal space and referencing them using appropriate wiki markup code.
