Ability to programmatically control embeds (#776)

* 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
