Hugh Davenport 637ccbec35 UI/Qt: Show search engine name in location bar
The placeholder text shows "Search or enter web address" which doesn't
tell the user about *how* the search will be performed. Other popular
open source browsers show the search engine that will be used. For
example:

	Chromium: "Search **engine** or type a URL"
	Firefox: "Search with **engine** or enter address"

This change changes the placeholder text of the location bar to show
"Search with **engine** or enter web address".
