Release v1.7.1-beta.1

• UI: Added right-click context menus to video cards. Thanks @them3rcury!
• UI: Fixed the game filter showing an empty list after the last video of a filtered game was deleted. Thanks @them3rcury!
• Rename: Fixed a brief flash of the old title right after renaming a video.
• Compression: Fixed compression keeping only the first audio track.
• Compression: Removed the "_compressed" file name suffix so compressed files keep their original name.

• Performance: Reduced frontend-to-backend messages to content ids so requests carry less redundant data.
