A user can submit a payment

After several hours of research, I've settled on stripe connect instead of crowd-tilt for payment processing, due to PCI compliance and IRS 1099 reporting features in stripe.

Installed stripe and created a simple payment page.
Oh - just noticed the amount in cents - yes, I did that, in both places where @amount appears, then reverted when the display broke. I'm sure I'll have to figure out why it breaks when I try to implement the real payments form in the projects page.
