Update window to version 4.2.6 (#75)

* Require window@4.2.6

* Set global properties as getters

Some properties will throw an error when accessed in certain conditions. We don't want to throw these errors, by accessing them when we setup the environemnt. Instead we should create getters for all window properties so they can throw the appropriate errors when accessed by user code.

* Update expectedProperties.json for window@4.2.6
