Refactor and streamline API and IPC protocol.
This patch removes the obsolete API support to send raw messages using a QWebChannel. Instead, it is encouraged to directly use WebSockets or navigator.qt. By doing so, we can cleanup the code considerably. While at it, the transport API is adapted to work on QJsonObject messages, instead of QStrings. This will allow us to use more efficient formats in e.g. QtWebKit or QtWebEngine. One could also implement a JSONRPC interface using a custom transport then.
