Cats typeclass instances for ArgumentMatcher.

Would be nice to also have tests that show how to use these, and that will also prove that the macro is not messing up with them.
We can even fix the macro so we can add a specific call for these

[ultrasecreth]

It would be just adding one or more strings to org.mockito.Utils.MockitoMatchers :)
in case they have symbolic syntax (ie *> or whatever) look at like 48 for an examples

[dangerousben]

I think stuff like this actually lessens the need for macro support, because the more convenient it is to combine and transform matchers, the less of a hassle it is to add in an argThat once done. I'll write up some example tests as suggested to test this theory though.

[ultrasecreth]

Of course, the less we rely on macros, the better :)

It looks like there is an issue with Scala 2.11

This is the output from CI, to test this locally you can run sbt clean +test (the + is what it makes it cross compile and run the tests in all the supported Scala versions)
