Title: Require the "message" param passed to a should[_not] call to be a string

Hi, this is related to #142.

I've added errors that will get thrown when message parameters aren't
strings. I couldn't find any specs dedicated to the should method so I
didn't add any specs. If someone can suggest a place where they should
go I'll totally add them.
