Jobee'sLair 0.2.3

Added

Link health: a game's download links are checked in the background while you look at its page or quick preview. Each check is a single HEAD request, sent only while no download needs the network. Check link health in the source list checks them all at once.
- A link that is gone (404 or 410, confirmed by a second request) is greyed out as Link unavailable and never picked.
- A link that keeps timing out is tagged Not responding and ranked after the hosts that answer.
- The best working mirror is picked instead. Rate-limited hosts are left alone, and nothing is marked on one failed request.

Space check for downloads of unknown size: most catalog releases don't state their size, so the free-space check before a download had nothing to compare against, and a download could fill the drive. The space is now checked again as soon as the server reports the size; a download that won't fit stops with "Not enough space" and offers Make Room. Its partial file is kept, so it can resume.
In-app updates:
- The new version now confirms it started as soon as it opens, not after the startup notice is closed. Before, closing the app at the notice could roll a working update back.
- A release whose files report a different version than its tag no longer loops. It fails once with the reason and isn't downloaded automatically again.
- The build now refuses to package an app whose package version doesn't match its version number.
Faster game pages: "More like this" is worked out once per game instead of sorting the whole catalog on every redraw (about 4x faster in testing).
