v0.9.1-dev.3

Dev build from the dev branch (heading toward 0.9.1). Not a stable release.

Changes since v0.9.1-dev.2:

• Playback: a new "Smooth Motion (Display Sync)" option under Settings > Playback > Advanced that paces video to your monitor's refresh rate, smoothing the judder and stutter you can get on displays whose refresh doesn't divide the content frame rate. Off by default; turn it on if playback isn't as smooth as another player.
• Diagnostics: a new Diagnostics screen under Settings > About. Turn on Diagnostic Logging, reproduce a problem, then copy a full report (system info plus a verbose playback and error log, with credentials stripped) straight into a bug report.
• Details: Play and Resume on movie and show pages are now the same expandable icon pills used elsewhere in the app, instead of a wide labelled button.
• Stability: fixed a crash that could appear when dismissing the Home/Remote server address dialog.

Tester build, report anything odd. The in-app updater's Beta channel will offer future dev builds automatically.
