By default whenever a Qt application is built with Qt Quick compiler,
it will scan all qrc resources for javascript files, generate
corresponding C++ code, and remove the original JS code. This is
problematic for web pages that are loaded in WebEngine because the pages
won't be able to access the javascript code, and silently fail (or if
you are lucky, you will get some unrelated "can not be found" error).

Use the undocumented QtQuick Compiler
QTQUICK_COMPILER_SKIPPED_RESOURCES qmake variable to specify that
Javascript source code found in qrc files should be left as is.

- Use the new signals and slots syntax, QStringLiteral, lambdas and nullptr.
- Use tr consistently for user-visible text.
- Use unprefixed CSS transform properties.
- Remove the "; undefined" workaround for runJavaScript calls, which is supposed
  to prevent a "possible recursion loop and crash" due to QVariant conversion.
  However, since no callback is passed to the method, no such conversion is
  taking place nowadays.

The name "fancybrowser" tricks people into thinking that this is the
reference browser example. But this example is a very simple browser
with an additional fancy content manipulation feature.
Rename this example to contentmanipulation to reflect reality.
