Deflect 0.12.0

• 143:
  The non-functional Servus dependency has been removed.
• 142:
  The DesktopStreamer app uses the full user name as the default stream name.
• 139:
  OSX: AppNap is now disabled for all QmlStreamers. The AppNapSuspender class
  is also available in Deflect library for use in external applications.
• 137:
  Deflect Qt: the offscreen Qml view used by the Qml streamer is available as a
  separate class.
• 133:
  QmlStreamer: Use asynchronous rendering, add
  deflect::qt::QmlStreamer::useAsyncSend() to enable asynchronous image streaming
  (off by default).
• 130:
  Replaced boost by C++11. Boost is now an optional dependency and it is used
  only by the tests. Some API changes were introduced by this change.
• 129:
  Cleared Deflect from boost::serialization that was used exclusively by Tide.
• 128:
  New events for transmitting all touch points in addition to existing gestures:
  • Gives the ability to handle more than one touch point in applications (e.g.
    draw with multiple fingers on a whiteboard).
  • Simplifies integration for applications that natively handle multitouch
    events, like Qml-based ones.
  • DeflectQt uses a new TouchInjector class for sending touch events to Qt
    (moved from Tide).
    In addition:
  • A new pinch event was added. Clients of Tide >= 1.2 have to adapt their
    code to use it instead of wheel events, which are no longer sent.
  • Minor additions to the simplestreamer demo application.
• 126:
  DesktopStreamer: The list of default hosts can be configured using the CMake
  variable DEFLECT_DESKTOPSTREAMER_HOSTS.
• 124:
  QmlStreamer: Users can now interact with WebGL content in a WebEngineView
  and no longer risk opening a system context menu with a long press (prevent
  crashes in certain offscreen applications).
• 123:
  QmlStreamer is now compatible with Qml WebEngineView items. Users must call
  QtWebEngine::initialize() in their QApplication before creating the stream.
  To receive keyboard events, the objectName property of a WebEngineView must
  be set to "webengineview".
  QmlStreamer also exposes the Stream::sendData() function and swipe gestures
  are available in Qml from a "deflectgestures" context property.
• 119:
  Added deflect::Stream::sendData() to allow sending user-defined information
  to the deflect::Server.
• 118:
  New "pan" event for multi-finger pan gestures.
• 117:
  Fix several issues with stream connection / disconnection [DISCL-375]
• 115:
  Bugfix for possible endless loop of warnings in ServerWorker::_flushSocket():
  "QAbstractSocket::waitForBytesWritten() is not allowed in UnconnectedState"
• 114:
  QmlStreamer: added support for keyboard events
