New Syntax for RSpec Mocks

[Sam Phippen]

Hi Everyone,

We've put together a new syntax for message expectations in RSpec
mocks. We'd like some feedback on how the defaults should be set. If
you could read this gist https://gist.github.com/samphippen/760812115d8be2e28995
(and the linked pull request), and comment we'd really appreciate it.

Thanks
