Typo and wrong version in dev dependencies

[Jakub Niewczas]

hi, while debugging other stuff i noticed that you have typo in dependencies. also i had to upgrade rspec version to get specs working
it should be:

s.add_development_dependency('rspec', '~> 3.0.0')
instead:
s.add_development_dependency('rpsec', '~> 2.9.0')
                          typo ^          ^ version
