Update (suggested) from RSpec should to expect.

Hi, I'd like to offer this suggestion for changes to the RSpec syntax to use expect.  More than just a style change, it has turned turned out that using 'expect' over 'should' is a recommended practice because of dealing with delegate/proxy objects as detailed in http://myronmars.to/n/dev-blog/2012/06/rspecs-new-expectation-syntax
As detailed in the blog post "In the future, we plan to change the defaults so that only expect is available unless you explicitly enable should. We may do this as soon as RSpec 3.0, but we want to give users plenty of time to get acquianted with it."
I changed the pattern matchers from =~ to match() as required for this change and while at it I also took the opportunity to change the == format to eq as recommended in the post. 
I switched from lamba {} to expect{} as detailed in http://stackoverflow.com/questions/4191016/which-style-lambda-should-or-expect-to-is-preferred-for-testing-expectations?rq=1.
I made these changes in the main spec/ files and also in the spec/watirspec files (approx 90+ files, 1000+ tests) which I forked seperately and will make a pull request for after this.  I realized afterwards that a branch would probably have been better.  Still learning.
All tests pass for both this and the spec/watirspec files.
