Patch: Option to hide service links to the node author

Hi,
I thougth it could be useful to implement an additional option in the settings page that allows to show/ hide the service links for the user's own nodes. Reason: I didn't want the users on my site to recommend/ share their own content but only those they 'stumbled upon'.
This patch was made against 5.x-1.1. I would be glad if you found this option useful and worth integrating it in the module.
Thanks!
