Contributing all buttons in one place goes against the designs that we
set out at the beginning of the project's rewrite and that multiple of
us have been following since then.

Prepare for React 16.

* feat(small-video): use InlineDialog for stats and remote menu

- Remove JitsiPopover and use InlineDialog instead.
- Bring the remote menu icon into react.
- Make vertical filmstrip position:fixed so popper (AtlasKit
  dependency) sets InlineDialogs and eventually tooltips to
  position:fixed.

* ref(remote-menu): hook KickButton to redux

* ref(remote-menu): hook MuteButton to redux

* modify padding, toggle dialogs

* pixel push margins to align dialogs, adjust padding of dialogs

* add comment about margin for dialog, add file I forgot

* modify indicator markup so the icon can be moved down while trigger stays at top of toolbar

* feat(indicators): move the "top toolbar" indicators to react

* wrap baseindicator

Move display of audio muted, video muted, and moderator icons,
which make up the elements of the small video toolbar, into React
Components.
