Public release blockers

[maxmilton]

The next public release is currently blocked due to:

• [x] Bookmark folder popups render off screen when too far to the right: #1121
• [x] Bookmark folder popups don't show and hide at the correct time: #1122
• [x] Bookmark folders don't look correct: #1120, #1123
• [x] Settings UI needs updating, doesn't need to be perfect but at least a basic refresh: #621
• [ ] Chrome Web Store listing needs updating: #1119, #259

I want to get all of these fixed before publishing the next public release. For anyone who wants to try intermittent versions you can go to https://github.com/maxmilton/new-tab/releases and manually install the latest release's chrome-extension.zip.

The Chrome Web Store submission was rejected due to an "unavailable privacy policy" so that needs to be resolved too, see issue https://github.com/maxmilton/new-tab/issues/1260.

Finally v0.18.0 is published and availiable in the Chrome Web Store :tada:

The store listing still needs updating with a better write up and images. Added an uninteresting screenshot as an interim image just to get published but it's a poor showcase of the actual extension experience. Keeping https://github.com/maxmilton/new-tab/issues/259 and https://github.com/maxmilton/new-tab/issues/1119 open until they're properly fixed.
