Possibility to add wildcards [Feature]

[jfalameda]

Hi,

It would be great to be able to add wildcards the parameters on the beenInvokedWith. For example.

expect(smoax).to.have.beenInvokedWith('POST', 'http:localhost', '*') The* should match localhost URL independently of the parameters the request was made with. This would simplify the test writing.

expect(smoax).to.have.beenInvokedWith('POST', 'http:localhost/*', '*') Also a wildcard or regular expression on the URL would be great.

Thanks.
