Removing reference to window object, to make oboe.js usable with web workers.

[paulsmithkc]

Line 2774 references window.location instead of location
Line 2788 references window.setTimeout instead of setTimeout

Simply changing these two lines so that they refer to the default global object instead window makes oboe.js usable in a web worker.
