[openstreetmap-website] Add welcome page (#338)

[Katie Filbert]

how about get rid of the "One Map, Many Uses" image?  sorry, but Stamen (for example) is not a use.  and it's kind of promotional and difficult to decide what to feature there.  

I think the text is more than sufficient and also makes for a bit less scrolling. :)
