Add finished() signal to AnimatedSprite

It's nicer to respond to a sprite finishing its animation like this:

    onFinished: doStuff()

than this:

    onRunningChanged: if (!running) doStuff()

In addition, the latter will get executed even if the animation
is manually stopped, whereas finished() is only emitted when the
animation finishes naturally.

[ChangeLog][QtQuick][AnimatedSprite] Added finished() signal to
AnimatedSprite as a convenient way to react to an animation finishing.
