- Accept downloads and add a downloads list.
- Fix toolbar icons being pixelated on hidpi screens by
  - enabling attribute AA_UseHighDpiPixmaps, and
  - replacing the 22x22 icons with 32x32 versions.
- Move favicon selection to WebView to reduce duplication.
- Replace UrlLineEdit with a standard QLineEdit using a QAction for the favicon
  and setClearButtonEnabled(true) for the clear button.
- Fix bug where the "File -> New Tab" action would create background tabs
  because the QAction::triggered(bool) signal was connected to the
  TabWidget::createTab(bool) slot with the bool argument having a completely
  different meaning between the two.
- Make the toolbar unmovable. Nobody wants to move the toolbar.
- Add tooltips to toolbar buttons.
- Add tooltips to the tab bar (page titles).
- Stop adding icons to menu items only to disable them right after.

Passing just command line options to Chromium prevents loading of the
initial startup url. This happens because the startup url is
overridden by the last command line argument, which happens to be a
Chromium option, thus an invalid URL.

Fix consists in using the last command line argument as the loading url
only if it can be parsed as valid url.

This example shows the use of QWebEngineView in a hybrid application,
and how one can leverage JavaScript libraries to provide functionality
with minimal effort.

QWebEngineView is used to preview a MarkDown document. The text is
exposed to the view through QWebChannel. An off-the-self js library
converts it to HTML.

The browser example already uses the name demobrowser internally, this
changes the external name to make it easier to refer to explicitly, and
avoid users thinking fancybrowser is the better example.

Qt copyrights are now in The Qt Company, so we could update the source

To match other modules example directory structures we should deploy our
examples in a directory matching the module name, webengine and
webenginewidgets in our case.

qmake uses the relative directory of each example up to the upper "examples"
directory to decide where they will be deployed when running the sources
install target.

Cleaner than deciding on startup with an env variable

This layers things properly to be able to implement the UI in the
example application instead of directly in shell_qt.cpp.

This is still using global variables to allow the Shell platform
code to do callbacks to the API classes. This should go away once
we properly implemented a WebContentsDelegate.
