Changing rspec syntax because that seems to be the future of rspec http:...

Hi folk after having read
http://myronmars.to/n/dev-blog/2012/06/rspecs-new-expectation-syntax

It seems like the `expect` syntax is going to be the future syntax for rspec, so I was considering if this was the way for us to go...

Even though I am most used to the `should` syntax I personally I don't have a strong opinion about this, but there are some good arguments in the blog, so I thought this might be the right opportunity to shift to the `expect` syntax,

Any opinions?
