We seemed to be using the names "film strip" and "filmstrip" (and,
consequently, their source code-conscious forms such as film-strip,
FilmStrip, etc.) In order to comply with our coding style which requires
a consistent one name for a given abstraction, choose one name and
rename the uses of the other name.
Wikipedia has a definition of a "filmstrip", I couldn't find a "film
strip". I guess our abstraction can be seen as what's described there.
When I google "film strip", I get results about "filmstrip" at the top.
That's why I chose "filmstrip".
Certain uses of "film strip" such as interfaceConfig.filmStripOnly and
in the external API I left untouched in an attempt to preserve
compatibility.
I wasn't sure whether CSS was tangled in compatibility so I made a
choice and renamed there was well.
Implements support for events for the API. Adds toggleChat and toggleContactList commands. Renames filmStrip to toggleFilmStrip command. Fixes issues with removing the embedded Jitsi Meet.
