Using HTML5 history gives a nil reference error

[grkuntzmd]

When I run

println(dom.GetWindow().History().Length())

I get the error

Uncaught Error: runtime error: invalid memory address or nil pointer dereference

but if I use

println(js.Global.Get("history").Get("length"))

the output is "2", as expected, both running in Chrome Version 66.0.3359.181 (Official Build) (64-bit), the latest version.

This is because window.History() is not implemented, see #41.
