Change lanterndonors's sponsor to adamfisk@gmail.com.

Since that is the user created by the seeding RemoteAPI script,
I assume it'll be present in all controllers.
Set pending status when launching sponsor instance.
Send proxy-ready email to sponsor.
Enable sending token, tweak related constants.
Register cron job to query for rally.org donations.

Also check SQS messages more frequently.
Restrict send_token endpoint to admin.
