Stops player update before sending stopping of shared video.

We used to stop player updates on self presence received, so between stop and self presence we can send a playing update which will provoke adding the video again to other participants.

The launch screen appears not centered and/or clipped on certain
devices. Unfortunately, I cannot reproduce it when I deploy the app to
devices and Simulator from Xcode 8.1. It may (or may very well not) be
that the Xcode version matters and the enterprise build server does
appear to use an older Xcode version.

Limit long display names

Hides all side panels before showing new one.

LaunchScreen.xib compiles locally with Xcode 8.1 but the enterprise
build fails. A possibility is that the enterprise build machine is
running an older Xcode version.

Incorrect password hint

fix: Use a separate css class for thumbnail menu

Log the page reload from one place

Adds a property to hide display name and disable update view.

Fixes casing of the tokendata directory.

Adds a property to hide display name and disable update view in SmallVideo. Localvideo hides displayName and disabled update view while users is editing its name and resumes normal behaviour when editing finishes.

Don't use Array.prototype.sort() because (1) it operates in place and,
thus, mutes the Redux state and (2) it is not necessarily stable and,
thus, unnecessarily shuffles the thumbnails.
