Stripe subscriptions need to be handled with dynamic url dispatch.

This commit begins the migration away from static dispatch.
Rename stripe subscription form and print out POST response.
Subscription with dummy accounts now works.

I think we have a basic integration with stripe.
cgi escape server rendered text
rename subcribe to subcribing

This change is necessary because leastauthority will process stripe-generated
subscription information with a different resource than the resource used to submit
the subscription request. That resource was: "subscribing.py", processing of the
result will be conducted by subscription-complete.py.
Redirect the POST request from subcribing to subscription-complete.
render_POST is now handled by the subscription-complete resource.
All handlers inherit from HandlerBase for logging.
Name secrets file after stripe customer id

Also place appropriate secrets within:
email to link to other data
Subscription plan
credit card id

Restored devpay signup to signup.py.

Document stripe flow, add log to subscr. complete.
Import start from subscription_complete.py.
