[Feature] Video player/UI enhancements

[Sleezus]

(Desktop) Anime Player

• Spacebar pause/Arrow key Seek (So I can seek and pause with the UI lock on)
• Resume progress on episode if not finished (Past 85% Completion or somthing)
• Keep the Lock UI button effects when episode changes
• Shortcuts for Skipping intro/Next and Previous, like Shift + S (Skip intro) Shift + N (Next), Shift + P (Previous)

(Mobile) Anime Player

• Add wakelock to mobile (I'm pretty sure you're doing this)

(Mobile) Homepage UI

• Standardize anime cover height so that all covers are the same height. (Making it look better imo)

Anilist

• Add a "Do not track" button next to the "Not This?" button for anilist, making it not track that anime, click said button a second time would re-enable tracking
• Also add back the Pop out player
