Fix style animations to stop when the animation target is hidden

QStyleAnimation automatically stopped for hidden QWidgets, but didn't
know anything about QQuickItems and kept animating regardless of their
visibility. This change ensures that style animations stop as soon as
the animation target no longer accepts the animation update eg. it has
become hidden or the window was minimized.

qdoc: Fix output filenames for QML basic type documentation

qdoc intends to prepend all html files related to QML with
a 'qml-' prefix. This doesn't work for basic QML types, as
those nodes do not have valid qml module name information.

This change fixes the issue by removing the requirement
for a qml module name, thereby always using the qml
prefix for a qml (basic) type.

iOS: fix crash when application quits

An application will sometimes crash if the keyboard
is told to hide while the application is about to
quit. This patch will ensure that we set m_qioswindow
(and [UIView qwindow]) to 0 when the window is destroyed.
We also check this pointer before telling QUIView to
resign first responder when closing the keyboard. The
latter will fix the crash.

iOS: fix crash when focusWindow changes while keyboard is open

It turns out we cannot rely on QGuiApplication::focusWindow() to
be non-zero at all times (e.g when pop-ups are closing etc).
So instead use m_focusView.qwindow which points to a
valid QWindow. This window is the same as QGuiApplication::focusWindow
most of the time, except when a focus window closes.
For those cases we get a new call to scrollRootView immediately
after with m_focusView updated to reflect the new focusWindow.
