Hi,

it would be great if this library would keep the settings consistent with other Google libraries.

We now have:

• A top level menu item called "Google" (which is a no-no to me)
• A Window -> Google item which only has the "Game Package Registry"
• A Window -> Firebase menu item
• A Window -> Google Play Games menu item
• An Assets -> Google Mobile Ads menu item

It would be really great if this was kept consistent. I personally would prefer if all Google things would live under "Window -> Google -> ".
