GTK Themes: Make the location bar area look native.

Replace the star and go buttons with a native looking thing, where
we manually draw the theme's button image for the full omnibox area
and then position the star/go buttons on top of that.

Also adds stand in versions of star_noborder and starred_noborder
until Glen can make real icons.
