Allow setTimeout(f) to support some JS libraries such as PDF.js.

Without this change some 3rd party JS libraries such as PDF.js, which rely on the nonstandard setTimeout(f), will not operate correctly.

According to MDN the delay argument is required. However browsers seem to treat setTimeout without delay argument the same as a delay of 0. This fix makes it so that Cappuccino apps do the same.
