Qeo Messaging library and HTML5 harness for Raspberry Pi

This is the Qeo messaging helper and HTML5 harness for Raspberry PI.
Requires QT

It does two things:
1) Instantiates a QWebView and hosts an html file passed in by the
user. A default one is checked in (QeoListener.html)
2) Listen to Qeo messages and forward them to the QWebView. Javascript
hosted within the QWebview can respond to the messages. See
QeoListener.html
