spy.called to accept call count to verify call count

[tinganho]

It would be convenient to have a function for

spy.called(6).times // returns true if spy have been called 6 times

Than I can use sinon-chai

spy.should.have.been.called(6).times

[tinganho]

And of course spy.called without function call should work as today

Use spy.callCount to check the number of calls.

@cjohansen There is a reason I use spy.calledTwice instead of spy.callCount === 2, because it is more readable. (Also it would play well with sinon-chai). Though I should maybe file the issue on sinon-chairepo instead.
