Enhancement to invite friends view

[cstiens]

@n8fr8 This is an enhancement to the view we already have. We've tinkered with ideas for circles, but nothing has stuck yet that doesn't require more views.

Copy for invite links: “Geneva has invited you to join a private group on Circulo. Circulo is an easy, safe way to check-in with your friends, family and colleagues. Download the app to join Geneva.”

Note: Considering that some may invite people over sms, we should possibly give a short version of the invite, or maybe the option to send the link only.

Copy for accepting an invite: By joining this circle, you agree to be responsive and give support to Geneva.
