[Membership 2 Pro] Social Network Login

1.-I need to give the option for visitor to register on a simply way with social network like facebook or google+, for no typing your data again.

2.- On settings whe "Hide admin toolbar" active, give the option for Logged in only one time, or create auto-log out when the people not activity for X time, bacause sometimes the people logged in many times on different devices, on a payment membership its not great that.
