Added shouldBeZero and shouldNotBeZero matcher for number types (#819)

Closes #819

I've also added the same matcher for floats (idn if it was necessary, because if it was not described on the task).
Also, there was a matcher file with just a couple of rules on the numerics package, so I joined with the existing one with more rules. Did the same with floats with to keep the same pattern from other numerics.

It looks great, just give another look about new line at end of file

The zero stuff is awesome and can be merged.
The float stuff needs change as per request.
Thanks!

[sksamuel]

Yes definitely.
