Migrate to event page

[kav2k]

Work started by @Vinne2, currently in branch event-page, is aimed at replacing the persistent background page with an event one.

In principle, this is doable, but there are many effects to consider.

• Finish transition of getCountersFromHTTP() to chrome.alarms
• Test optimistic retry (Optimistic retry #22) with 1-minute granularity
• Consider effects of transition for storage.js, i.e. state
• Transition saveToStorage() to chrome.alarms (see syncRetryTimeout)
• Consider top-level code in background.js
• Consider ALL global state in functions.js

This is a non-trivial task, all in all, even not considering impact on #22.

Any progress on that here?

Work must've pulled me away from this long ago and I totally forgot about the case. Now I've been checking my extensions and have just started filing issues about moving them to be persistent:false and came back to this. I fell like in a timeloop…

Nope, no progress. I haven't touched this extension in years (because it works as-is).

I'd like to make a pull request to the branch event-page here for you to see my work, but the branch is 4 years behind the master. Should you update the event-page branch from master or should I make a pull request anyway? See the problem: https://github.com/knyar/theoldreader-chrome/compare/event-page...Vinne2:event-page?expand=1 The diff gets cluttered with all the 4-years' commits.

Disregard the event-page branch here (I'll delete it), PR off the master.
