Simple browser example: Fix up the code

- Remove duplicated unused helper questionForFeature()
- Replace lambdas by slots where possible
- Fix clang warning about using multiple arguments to QString::arg()
- Remove dead code in WebView::contextMenuEvent() which checks on
  inspectElement == actions.cend(), but is within an "if" checking
  the same condition.
