When purchasing multiple courses (especially with bundled Program purchase) the donation box shows up multiple times. Donation box should only show once regardless of number of courses purchased.

Input forms that need validation will have AJAX requests
performed to get validation decisions live.
All but a few important and common form fields perform
generic validation; these will need a back-end handler
in the future in order to have them validated through AJAX requests.
Information is conveyed on focus and blur for both
errors and successes.
In particular, implement a validation API for registration,
where a client makes AJAX calls to the endpoints requesting
validation decisions on each input. Responses are strings
dependent on the type of validation error; if no error,
then empty string to indicate OK.
The function `create_account_with_params` calls `_do_create_account`,
which exhibits some discrepant behavior with throwing errors when handling
duplicate email and/or username.
A duplicate email raises a `ValidationError` (rather than the expected
`AccountValidationError`) from the first part of `_do_create_account`,
when errors from `form` (the `AccountCreationForm`) are raised.
A duplicate username raises the expected `AccountValidationError`, but
from a later part of `_do_create_account`. As a result, registering with
both duplicate username and email raises a `ValidationError` for email only.
The user message for username is “An account with the Public Username
'{username}' already exists.” which differs from that of email, “It
looks like {email} belongs to an existing account. Try again with a
different email." The latter is more consistent with other user messages.
PSA was monolothic, now split, with new features, like
a DB-backed partial pipeline. FB OAuth2 version also upped.
Partial pipelines don't get cleared except when necessary.
They persist for special cases like change of browser while
still mid-pipeline (i.e. email validation step).
Refactor, cleanup, and update of a lot of small things as well.
PLEASE NOTE the new `social_auth_partial` table.
Defaulting to a plaintext response makes no sense for an endpoint that is intended to be used by machines for testing. The endpoint now returns JSON only unless a redirect action is triggered.
