Redesigned popup: see at a glance whether the app is running, pick a quality with its size and download in one click, and see what the app is downloading right now. New icon. Options page reorganised. No new permissions.

Pages with no video on them are now answered instantly.

Opening the toolbar popup on a YouTube search page, channel, or the home
page used to ask the desktop app to look for downloadable video there.
Those pages contain no video, so the answer was always "nothing" — after
a long wait, and after a great deal of pointless network traffic that
could get your connection rate-limited by the site.

The popup now recognises such a page immediately and says so, without
contacting the app at all. Pages that do hold a video are unaffected.

Fixes a case where a video page could still offer a generic "Stream" download
instead of the quality list. The previous release hid those links only while
the quality list loaded successfully, so they reappeared whenever the desktop
app was restarting or not running. They are now withheld in all cases. The
toolbar badge also no longer counts links that are never offered.

Fixed: on some video pages the menu could offer a generic "Stream" download
instead of the list of qualities. That link points at one internal piece of
the video rather than the video itself, so it produced a broken or silent
file. Those links are no longer offered.

Improved: the popup now loads the available qualities as soon as you open it,
instead of waiting for you to press a button.

Improved: when the Downloader Pro desktop app isn't running, the popup now
says so clearly, instead of quietly falling back to showing raw stream links.
