Jitsi Meet doesn't seem to work with c2s_require_encryption set to true.
c2s_require_encryption is false by default. However it is possible that
in some Prosody configurations it is overriden by a global config to be
true. In that case Jitsi Meet might not work out-of-box. So let's set it
explicitly to be sure it is correct.

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.

Also clears debian package from including *.js files from source roote folder, files which were not used.

This is to help understanding how things are wired.

- use proper punctuation
- fix markdown syntax
- always use syntax highlighting
- document missing commands
- miscellaneous grammar fixes

Use Maven in place of ant
Add --host parameter for jicofo
Add build for jitsi Meet

Revert "Force jquery-ui version to fix pb with beta version we can get with npm"

This reverts commit 35a8641e62.

It makes for a bad first-time experience for users, since the desktop sharing
button will be visible, but it will never work.

Also get rid of the now deprecated `desktopSharingChromeMethod` option.

Fix videoConferenceJoined and videoConferenceLeft event names

Adds the --host argument to the jicofo command, as suggested by exs on irc.

Now the web app can be installed separately from jicofo and jitsi-videobridge, or can be installed on machine running nginx or apache. Currently only nginx will be configured and apache config is left to user. Later we can add and the apache config. Renames jitsi-meet to jitsi-meet-web (just the web content) and jitsi-meet-web-config (configuring jetty, nginx or apache). A new jitsi-meet package will be introduced, a meta package depending on jicofo, jvb and the current packages.
