Subject: [PATCH] strict mode

Should fix usage with bundles including bunyan and using strict mode.
Had to fix a surprise effect that 'window === this' is no longer
true in strict mode:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Strict_mode
"""That means, among other things, that in browsers it's no longer
possible to reference the window object through this inside a strict
mode function."""

Fixes #236, #231, and #223.
