Remove multiple specifications of gem 'rspec'

We should take advantage of bundler. Use gemspec in the Gemfile to merge the Gemfile with the dependencies in the .gemspec file.
This solution requires rcov to be removed from .gemspec because RCov only works in MRI 1.8 and there's no way to specify platforms in the .gemspec.
