Add documentation for the QtWebChannel module.

Please proof-read it and tell me what needs to be improved. I assume
most people will probably not use the QWebChannel directly. Rather, they
will only consume its features indirectly through the integration in
QtWebKit/QtWebEngine. Thus the documentation here is for QWebChannel as
a library. User-end documentation should be added to QtWebKit, I think.
