gAdds the files that implement the HTML5 Database API to the

project. Also adds stubs for the integration with the renderer.

Right now, the integration is done by just replacing two key
cpp files: DatabaseTracker and OriginQuotaManager. Once this
all gets up and running, I'll circle back and think about the
changes necessary to WebCore to do a more elegant integration.
