Add back POST_update for API clients.
Retrieve deleted users with paypal gold subscriptions.

They won't get any gold but the event is logged so the subscription
can be deleted. Respond to paypal's IPN with a 200 rather than
raising an exception so the IPN isn't retried.
VLocation: strip out "null" values.
Delete unused describe_jobflows_by_ids.
emr_helpers: Avoid calling describe_jobflows() with no filters.

Replaces a catchall call to emr_connect.describe_jobflows() with
calls that specify states or jobflowid. This will reduce the size
of the response, which AWS has warned could trigger 400 errors.

charge_transaction: Check error value from _make_transaction.
Record rejection reason in PromotionLog.
promotelinkform: Increase default budget to $50.
Handle AuthorizeNetException in edit_profile.
