swift: Add discovery & invites to the todos app

Adds advertising to the todos example app, an invite handler that
auto-accepts all invites, discovery that shows nearby users as
well as all their contacts in their address book, and the invite
logic for a given discovered or addressbook-based email.

This CL also includes the following other fixes:
- Adds a public init for SyncgroupInviteHandler in Syncbase.framework
- An initial set of app icons. We need to include more sizes for
  various devices.
- Removes an assert that was invalid in Syncbase model.
