Fix the UI when anonymous domain auth is in use

feat: Enables by default tab sharing for chrome.

Update api.md. There is still work to be done, cause handling parameters in executeCommand is not currently correct and needs fixing. But for now displayname is the only command that requires a parameter.

Add 'build' dir to jshintignore

fix(PageReloadOverlay):Basic layout fix

Updates debian packaging.

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.

Sending unpin after clicking local video and unpinning remote.

Authentication buttons no longer belong to the Toolbar.

Fixes unpinning local user which is dominant speaker.

If we:
 - pin a remote and click it, unpin is signalled.
 - pin a remote and the click another remote, the new one is pinned and signalled.
 - pin a remote and then click local. UI pins local, but unpinning remote is not signaled, fix addressed with this commit.
 - pin/unpin local, nothing is signalled.

Makes close button non-focusable.

It was not switching and staying on local video on unpinning, after change the last shown video will be used to switch to it.

Prevents the close button to take focus while user clicks tab in the page, which will privent the toast to be closed.

Fix popover

Removes click handlers when popup is hidden.
