Because of weird interaction between deleteLater(),
Qt::WA_DeleteOnClose, and QQuickRenderControlPrivate::windowDestroyed()
which executes all the deferred deletions at a bad time, there were
some use-after-free crashes.

The workaround is not to close the window when the last tab is closed,
but rather create a new tab, like the behavior was on non-macOS
platforms.

Previously when Airplay was activated and a new QWebEngineView instance
was created, a black area would be rendered inside the view.
This happened because of incompatible OpenGL contexts. The global Qt
OpenGL context could not share its textures with the newly created
"after-airplay" context, due to the contexts being used by different
GPUs (only possible on a MacBook Pro).

The fix is to add the NSSupportsAutomaticGraphicsSwitching option into
the application plist file, which informs macOS that the application
supports usage of dual GPUs, and thus allows sharing of contexts
across GPUs.

Current implementation of history manager seems to
be not straight forward. To display history we use QList to keep
history items plus model adapter in form of HistoryModel
(QAbstractTableModel) plus HistoryFilterModel to avoid
duplication, plus HistoryTreeModel to make a tree view with
split for dates, plus TreeProxyModel on top to enable
sorting. This approach unfortunately falls apart when items
should be deleted from the model by treeView. This ends
badly with corrupted cached values.

This fix removes history items using history manager.
It also abandons HistoryTreeModel since frequent sourceReset calls make
it unusable. If split for dates it desired the better approach
would be to implement history tree model already at HistoryManager
level to avoid unmaintainable code.
