After looking at the jquery-ui documentation, I believe it
is being used only in one place, when toggling the smiley
menu. That toggling has been quickly replaced with a normal
jquery call.

Note: @atlassian/aui also uses jquery-ui but killing that
off will be more difficult due to its CSS being used.

Everything strophe related is now handled in lib-jitsi-meet project.

* feat(notifications): implement a react/redux notification system

* squash into impl explicit timeout, style

* ref(notifications): convert toastr notifications to use react

* ref(toastr): remove library

* squash into conversion: pass timeout

* squash into clean remove from debian patch

The counterpart of the external API in the Jitsi Meet Web app uses the
search URL param jwt to heuristically detect that the Web app is very
likely embedded (as an iframe) and, consequently, needs to forcefully
enable itself. It was looking at whether there was a JSON Web Token
(JWT) but that logic got broken when the JWT support was rewritten
because the check started happening before the search URL param jwt was
parsed.

The transport module will be handling all external app
communication.

It's no longer needed for building since Node >= 6 already has the minimum
required ES6 syntax. In addition, drop it from app.js since we use Webpack with
the Babel loader to transpile ES5 to ES6.

The React-based rewrite looks whether there's a room name (in the
window's location) in order to choose between WelcomePage and
Conference. But app.js expects Conference to be rendered before it
builds a room name if WelcomePage is disabled and there's no room name.
A quick and dirty workaround is to render Conference within WelcomePage
so that the rendered result closely resembles index.html before the
React-based rewrite.

Converts ConferenceUrl to a class and binds an instance to the global
APP variable, as requested by HTerezov.

We need to make sure that on the page reload all original parameters
used to load the conference are preserved. New modules helps to manage
different types of conference URLs like the one used for invites and
the one for reloading the page.

Enable ESLint on jitsi-meet with the same configuration and the same
goals as in lib-jitsi-meet.

Use location.href instead of location.pathname to make the URL absolute
