Doc: Fix example documentation and paths
To fix issues related to example documentation and to follow Qt convention, do the following changes: - Rename examples/qwebchannel to examples/webchannel - Move example-specific documentation to correct location(s) - Include generic 'Running the Example' instructions - Add the module name to example title, fix links This ensures that example docs are built and the example manifest file generated correctly.

+This is a small NodeJS implementation on how to connect to a QWebChannel.
+
+This example implements a small chat client using the command line. It connects
+to the server provided by the other example 'examples/standalone/standalone'. Of
+course the port the server listens on must be known.
+
+How to run it:
+
+- Install NodeJS (at least 0.10.x) (http://www.nodejs.org/download/)
+- go to examples/nodejs and execute "npm install". This sets up the nodeJS
+ environment in this folder
+- ensure examples/standalone/standalone is running
+- execute the example with "node chatclient.js"
+

+/*!
+ \example standalone
+ \title Qt WebChannel Standalone Example
+ \ingroup qtwebchannel-examples
+ \image standalone-screenshot.png
+ \brief Shows how to use the QWebChannel C++ API to communicate with an external client.
+
+ The standalone example is a simple chat between a pure C++/Qt application and a remote HTML
+ client running in your default browser.
+
+ \include examples-run.qdocinc
+
+ \section1 Overview
+
+ The C++ application sets up a QWebChannel instance and publishes a Dialog object over it.
+ For the remote client side, \c index.html is opened. Both show a dialog with the list of
+ received messages and an input box to send messages to the other end.
+
+ The Dialog emits the Dialog::sendText() signal when the user sends a message. The signal
+ automatically gets propagated to the HTML client. When the user enters a message on the HTML
+ side, Dialog::receiveText() is called.
+
+ All communication between the HTML client and the C++/Qt server is done over a WebSocket.
+ The C++ side instantiates a QWebSocketServer and wraps incoming QWebSocket connections
+ in WebSocketTransport objects, which implement QWebChannelAbstractTransport. These objects are
+ then connected to the QWebChannel instance.
