display on-site notification re: credit card failure

[duckinator]

[was: Lack of information about failed transactions]

The only indicator I got that a transaction failed was this:

If I hadn't gone to somebody else's profile, I would have never found out that the transaction had failed. I can't even reliably determine which transaction it is that failed.

As a side note, "Fix your" is a separate link from "credit card", and the "Fix your" link merely goes to #. :)

If you click "credit card" it should link you to https://www.gittip.com/credit-card.html which should tell you your error.

It does, and it shows me this:

Payment Required: 402: 349: Do Not Honor Your request id is [...]. -- Do Not Honor.

(Where [...] is the request ID, which I removed because I don't know what exactly it is.)

Between how cryptic that is (I believe it boils down to my bank [it's a debit card] basically replying with "LOLNOPE"?) and the fact that it doesn't have any sort of notification -- neither via email nor when you are on Gittip but not on someone else's profile -- that mentions it, it's very difficult to notice. That little message doesn't stand out at all, and is only on other users' profiles. I talked to @seanlinsley briefly on IRC and they mentioned that #89 is a long-standing issue related to why we can't email people, and #1643 is already in master and could be useful for notifying users when they visit the site.

If we were to use #1643 for this (which makes sense to me), I'd say we should look into a way to have "sticky" alerts (always show them until they are explicitly acknowledged in some manner).

Ftr, notifying users of payment errors via email is #583.

[chadwhitacre]

I take it this issue is about notifying users via on-site notifications.

Title updated.

Note that @rummik implemented sticky notifications, so we should have everything necessary to implement this, now.

To clarify for anyone reading this later, we have notifications for impending credit card expirations (#2379), but nothing for failures
