* Added Window.Open and window.SetLocation methods for the Window struct + `window.open` : https://developer.mozilla.org/en-US/docs/Web/API/Window/open#Syntax + `window.location = someURL` * Accept the window features as a key value map pair in the Open function * Changes for the review + string type for the other params + Use strings.Join to make the windowFeatures string * fix code style
