Update to the lastest version of Mocha

Mocha no longer defines a global variable named `global`. This library
never should have depended on it in the first place; that was a bug.
Update to latest QUnit (v1.14.0)

From the 1.13.0 change log:

> Logging: Add runtime property to testDone, deprecate duration
