promise comparisons (v102)

Revision 102 of this benchmark created 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.
