AmpSonic: Self-Hosted Music

Fixes - Fixed a song showing as downloaded without its file when the recently played cache removed it during the download. Offline, playback stopped at that song. - Fixed a download stopping at a song the server can't send, such as one whose file is missing. The other songs now download, and the error no longer comes back after each library refresh. - Fixed playback stopping after you removed every song after the current one from the queue. AutoPlay now adds songs again. Clear Up Next still stops AutoPlay. - Fixed a smart playlist row on Home playing and shuffling only its first 12 songs. It now plays the whole smart playlist, and offline it shows the playlist's downloaded songs instead of disappearing. - Fixed tapping an album in a playlist shown as albums opening the last album in that line instead. - Fixed Airsonic-Advanced servers refusing to connect with "Incompatible REST protocol version", and their albums, artists, and songs loading empty. - Fixed an open playlist showing only its downloaded songs, or "not available offline", after the server answered or the app went back online. The page now shows the full playlist without opening it again. - Fixed a widget or control doing nothing when its action failed, such as while AmpSonic was still connecting or when the playlist was empty. AmpSonic now shows what went wrong when you open it. - Fixed the waveform in the player drawing itself again, and starting its analysis over, each time you opened the player. - Fixed Shuffle being undone when you turned it on or off while the next song was loading. The songs now play in the order the Shuffle button shows. - Fixed AmpSonic staying without a server after it opened while the server was restarting or behind a Cloudflare Tunnel that was down. It now shows your library offline and connects again by itself once the server is back. - Fixed some plays made while offline being sent to the server twice, which counted them twice in play counts and Most Played.
