- The `rateChange` event now logs the updated speed,
not just the time at which it occurred.
- The `scrub` now (more) accurately logs the position
it came from before the destination.
- The recsys events get consolidated for logical consistency.
## Issue
One of the items in 5865 Video shortcut issues
This one is not really an issue, but it would be nice to match what the arrow keys are doing. Also, in slower regions, seeking 10s will almost always end up buffering.
Also restores the CSS for vjs-overlay which I commented out previously for *some* reason (but I don't know why, and it doesn't seem to make a difference whether I comment it out or not)
Adds custom video.js hls quality selector plugin
This allows the quality selector plugin to stay active and listen for source changes on the player to prevent the need to recreate the player when switching between MP4's and M3U8's
## Issue:
5119 "Video: Mobile UI + overlay for keyboard shortcut feedback" was disabled because the feature broke the chromecast button in Android Chrome
