Enable friendly message when users Distro/Arch not supported

[Anthony Lenton]

It would be great to display a friendly message on the campaign "Thank You" page, if we know the user is on a distroseries that the campaign doesn't support.

As campaign templates are stored in the DB this could be updated through the web, except that there currently isn't a context variable that reports the user's distroseries.

It would be great to provide this context variable, so that campaign templates can display friendly messages when the user is running an unsupported distroseries.

I'll add a branch with a test demoing that this does work without a code-change.

15:16 <noodles> So what does the bug require that the current implementation doesn't do? A per-campaign flag, instead of per-app?
15:17 <achuni> yep
15:18 <noodles> Why not use the unsupported_apps context variable? ie.
15:18 <noodles> Currently it already shows you for each app if it's not available, but you could also add at the top, without any code change:
15:19 <noodles> {% if unsupported_apps %}<p class="whateverflag">Some of the applications are not available for your computer.</p>{% endif %}
15:20 <achuni> yeah
15:20 <achuni> and something similar for when all apps are unsupported
15:20 <noodles> yep {% if apps == unsupported_apps %}...
15:21 * noodles checks if they would be equal lists in that case.
15:21 * achuni will give that a try
15:21 <achuni> sigh
15:21 <achuni> ...at some point
15:22 <noodles> I can check it out tomorrow, I just want to make sure I'm not missing something from the bug.
15:27 <noodles> Yep, according to CouponFormForUser, the two lists will indeed be equal when none of the apps are supported. I can add a test demoing it to the bug, or if there is something else required for the bug, just say so on the bug.
