Update many icons (#2413)

* Replace and update Windows Server icon

* Update Microsoft logo

It bugged out in some cases (not entirely sure why) and had a background colour.

* Update Google Sites and WebDev logo

* Update Google Maps icon and remove Google Search Appliance

Since Google Search Appliance has been stopped by Google, its not worth tracking now.
