Setting localStorage throws in Safari private mode

[levithomason]

Per the gitter issue from @eliasliedholm:

Hi, I’m running into a problem when using Stardust in safari private mode, because safari does not allow the debugger tool to write to the localStorage object, and will throw an exception. I found that in runtime, process.env.NODE_ENV is undefined, so the debugger will be added even in production, which means safari private mode will always crash.

Was wondering if you knew a way to get around it?

We use debug for this and this is a known issue with the way it is configured in the browser: debug-js/debug#167.

I'm adding this as a bug. We should wrap our localStorage use in a try/catch.
