Device Selection re-uses the local video track for its preview.
When displaying Device Selection while video muted, the text
"muted" displays within the video preview, but some translations
may mistake this to mean audio muted. The text has been changed
to be explicit about video mute. This is a temporary solution;
at some point Device Selection should not re-use the local track
except for IE, the one browser that cannot get multiple tracks
from the same video input.

Fix spelling/grammar for  micConstraintFailedError and cameraConstraintFailedError

The Device Selection modal consists of:
- DeviceSelection, an overly smart component responsible for
  triggering stream creation and cleanup.
- DeviceSelector for selector elements.
- VideoInputPreview for displaying a video preview.
- AudioInputPreview for displaying a volume meter.
- AudioOutputPreview for a test sound output link.

Store changes include is primarily storing the list of
available devices in redux. Other app state has been left
alone for future refactoring.

Moves the P2P indication next to the remote IP address
and rewords it to "(p2p)".

#1411

Will show (direct) next to the UPD or TCP transport type if we're
running on P2P connection.

* Handle last n in the client

* fix(LargeVideoManager,RemoteVideo): Syntax errors

Firefox (at least) renders it verbatim.

Updates transport type to show multiple values as we do for addresses and ports.

Split language detectors to be web/native dependent. Take care of strings that contain html.

Removing translateString forces using data-i18n attributes, to make sure we do not forget to set them. Missing data-i18n attributes is a problem with late loading where we can end up without translation, without text. Missing data-i18n attributes is also problem that strings will not be translated when changing language.
Fixes a bug in invite dialog, where remove password button was shown for non moderators.

Will disconnect on ConferenceErrors.VIDEOBRIDGE_NOT_AVAILABLE.
Show the same message when either JVB is not available or Jicofo
disconnects.

Grey filter will be applied to the remote video/avatar displayed on
"large" and a message indicating remote connectivity issues will be
shown on top of that.

There is sometimes problems with cache and late loading of the translations, this commit avoids showing translation key in the contactlist title, by moving the parameter into the code.

Uses the same display names in the contact list as in the thumbnails, for local and remote.
