quality of life, remote control options and more responsiveness

• Add about site (in Settings with current version but feel free adding stuff there!)
• Switch for disabling/muting Preview Videos in settings.
• Save position/render when returning from Video or returning from Conference Grid to Event List
• No animation when pressing play after it got paused (should hide controls immediately without showing the play button turn into the pause button)
• Lazy loading of the event list with buffer
• Changing font sizes/padding to relative values and fiddling around with scaling (hope this looks alright... no idea if there aren't strange corner cases that cut off hover borders)
• New screenshots (probably not in the right AR)
• Player buttons/controls inspired by Youtube/Jellyfin (e. g. back from the Video, pressing back in Home to close)
• Pause Video playback, when pressing language/subtitles (460! And probably maybe even 799 too... aaaaaaaaaah. Had to finally link to the lginputhook guy's gist after I was using it way too often and in this https://github.com/torvalds/linux/blob/master/include/uapi/linux/input-event-codes.h. But reading input events was useful.) button on the remote
• Aligned language/subtitles selector design with Settings and using a checkmark fontawesome icon instead of "current".

What I would love to see or implement:

• Reducing app size.
• Faster loading! (I am not sure if there is a way to improve it even more tbh).
• Sometimes after the controls hide/close it needs to press on back on the remote control to exit a video. (it's the debounce when hiding controls)
• Improve/modulize jsx and CSS can 100% be consolidated at some point.

No one wants to troubleshoot CSS that isn't supported in Chrome 68 (or even older) anymore.... (like gap!). Yeah yeah I know I know we should support it. Otherwise it isn't running on my own TV.

Ah sorry that last version iteration slipped my commit (Is this something people say? At least I didn't commit my build script haha
