Doc: Fix documentation issues

The Qt Widgets Application example was moved to manual tests,
and no longer contains the snippet identifiers. Fix \snippet
and \quotefile commands to quote similar code snippets from
other examples or snippet files.

Fix also the following documentation warnings:

* No such parameter 'parsingMode' in QUrl::fromEncoded()
* Missing image: rsslisting.cpp

Pick-to: 6.6 6.5
