Diffractor 1.27.1

• Fixed a crash affecting some users on startup.
• Uses much less memory while browsing and viewing.
• Ratings and keywords cannot be lost to a locked sidecar — a .xmp that cannot be read is refused, not rebuilt from the edit alone.
• Duplicate detection stops fading out — scrolling a video into view no longer clears its checksum.
• Video plays in software rendering — with hardware acceleration off.
