promise comparisons (v78)

Revision 78 of this benchmark created by Matthew Robb on

Description

This is a comparison of different promise libraries, performing the most basic tasks of creating a promise, adding a then handler and then resolving the promise.

Recent benchmarks deliberately cripple bluebird but didn't force the same method on other libraries.

*Added ES6 Promise polyfill
