This reverses the policy that was set, but incompletely enforced, by
commit 951514dd7d. The self-closing tag
syntax is clearer, more consistent, simpler to parse, compatible with
XML, preferred by Prettier, and (most importantly now) required by
FormatJS.

This fixes some issues with unclear terminology and visual styling in
the pages for the new free trial.
There's probably more we can and should usefully do in the future.
This sidesteps tricky escaping issues, and will make it easier to
build a strict Content-Security-Policy.

This is a major rewrite of the billing system. It moves subscription
information off of stripe Subscriptions and into a local CustomerPlan
table.
To keep this manageable, it leaves several things unimplemented
(downgrading, etc), and a variety of other TODOs in the code. There are also
some known regressions, e.g. error-handling on /upgrade is broken.
The fixture changes are because self.upgrade formerly used to cause a page load
of /billing, which in turn calls Customer.retrieve.
If we ran the full test suite with GENERATE_STRIPE_FIXTURES=True, we would
likely see several more Customer.retrieve.N.json's being deleted. But
keeping them there for now to keep the diff small.
The actual implementation of the change will be a cron job that runs once a
day and generates invoices for anyone with an account_balance > 0.
There are currently no tests for that part of the flow, so no tests had to
change.
