* Separated "Other Videos" section into a dedicated component/service
I'm currently working on some proof-of-concepts for recommendation
providers that could work with PeerTube to provide useful video
suggestions to the user.
As a first step, I want to have great clarity about how PeerTube,
itself, will surface these videos to the user.
With this branch, I'm refactoring the "recommendations" to make it
easier to swap out different recommender implementations quickly.
Stop recommender from including the video that's being watched.
Ensure always 5 recommendations
* Treat recommendations as a stream of values, rather than a single async value.
* Prioritize readability over HTTP response size early-optimization.
* Simplify pipe
- make the placeholder disappear on focus in the search bar
- make the placeholder disappear on focus in the comment textarea
- make the texarea resize automagically
- refactor the watch view to use bootstrap 4's flexgrid
- move action buttons of the watch view to the right of the video info
- responsive tweaks and margin adjustments in the watch view
* first stab at jschannel based player api
* semicolon purge
* more method-level docs; consolidate definitions
* missing definitions
* better match peertube's class conventions
* styling for embed tester
* basic docs
* add `getVolume`
* document the test-embed feature
* Replace angular-cli patch with something less risky
* path.join() is needed, provide a naive implementation
* technically, webpack provided a polyfill for Buffer, we should too
* process polyfill matches webpack; peertube depends on nextTick
* polyfill for path to match webpack
* http/https polyfills as per webpack
