Add an "asynchonous" property to Image.

Allows loading/decoding local images in an asynchronous thread (already
the case for network images).

+    \qmlproperty bool Image::asynchronous
+
+    Specifies that images on the local filesystem should be loaded
+    asynchronously in a separate thread.  The default value is
+    false, causing the user interface thread to block while the
+    image is loaded.  Setting \a asynchronous to true is useful where
+    maintaining a responsive user interface is more desireable
+    than having images immediately visible.
+
+    Note that this property is only valid for images read from the
+    local filesystem.  Images loaded via a network resource (e.g. HTTP)
+    are always loaded asynchonously.
