videojs: refactor i18n (breaking up 'events' file)
## Issue I couldn't find where the i18n went because the "events" refactor is just as confusing as the original -- unrelated things are still lumped together in a file. Also, factoring based on events isn't useful -- it is features that drive what events are needed, not the other way around. This forces features to register events here, and do other things elsewhere? It will be more intuitive to have a one-file-per-feature structure. ## Change Use existing frameworks to encapsulate things to manageable units/features: (1) the React useEffect files (can be used isolate out React features like 'tap-to-mute' handling). (2) the videojs plugins framework.

/**
|
||||
* Although videojs has its own i18n system, it is not trivial to pass our
|
||||
* translation data to it. Instead of maintaining two sets of localization
|
||||
* systems, we'll just ignore the videojs one and update the strings ourselves
|
||||
* through events.
|
||||
*
|
||||
* We use events because that's the only way to update components with dynamic
|
||||
* text like "Play/Pause" in videojs. We can't just define the set of texts at
|
||||
* initialization, unless we use custom components to do that.
|
||||
*
|
||||
* For the case of 'MuteToggle', videojs changes the text at 'loadstart', so
|
||||
* this event was chosen as the "lowest common denominator" to update the other
|
||||
* static-text components.
