No longer touching internal GMaps DOM elements.

Simple and effective: As soon as a map has a Google layer, the whole map viewport is added as control to the GMap. As soon as no Google layer is visible on the map any more, the map viewport is appended to the map container again. With this change, OpenLayers strictly limits its GMaps integration to the GMaps API.

Also note that there are no css overrides for the attribution any more. Instead, controls can now be conditionally positioned differently for Google layer by using the .olForeignContainer selector.
