v0.7.3-rev2

• Fix: certain home hubs were limited to 10 items without pagination
• Fix: very rare infinite playback loop with enabled embedded subtitles (thanks @florinvlaicu for reporting)
• Fix: Partially fix issues when switching audio streams during Transcoded/DirectStream playback
• Fix: Fix error in ExtendHubTask
• Fix: Partially revert "Home: Increase section change timeout from 0.3s to 0.5s; re-jig section change handling to allow using ENTER/SELECT to immediately select a section below 0.5s wait time" due to instability
• Fix: Fix a couple of SyntaxWarnings for invalid escape sequences
• Fix: Unfocusable buttons throw focus errors occasionally on shutdown
• Fix: Laggy UI after playback/5 minutes due to requesting certain hubs without limits applied. Drastically improving UI smoothness even for smaller hubs (<1000 items)
  This also fixes crash and shutdown issues and by proxy should enable everyone to use a poster resolution scale of at least 200%.
• Fix: Depending on the situation, the home hubs update request could be sent multiple times while waiting for the first one to finish. (thanks @bowlingbeeg)
• Subtitles: Supply OpenSubtitles.com hash if possible and enabled
• Subtitles: Add setting to Audio/Subtitles to calculate the OpenSubtitles.com hash (default: off)
• Core: Advanced Settings: make default resolution scale a percentage; limit to 750% max (based on Plex max poster size)
• Core: Add more debug logging for player events
• Core: Add more debug logging details for hub refresh events
