Add the icon from GNOME Contacts

[hmlendea]

Hello,

Could you also include the icon for GNOME Contacts into this pack?
I'd very much like to use that one as the icon for the Contacts app, so that it's the same on my desktop and my phone.

Thank you.

PS: In case it somehow already is, please tell me how I can find it, because I looked for it a lot and I just can't find it.
