Use Gemfile for development deps rather than gemspec.

- To make it work properly for all platforms I had to
  include conditionals in the gemspec. That's pretty
  weird as the gemspec needs to be eventually compiled
  into a static file at gem release time.
- Relax version specifiers to use `>=` rather than `~>`.
  While the latter is the recommended way, I want to be
  able to use `bundle update` and update to the absolute
  latest version of a gem w/o having to research if a new
  minor or major version has come out. Plus, the Gemfile.lock
  is in source to ensure gems aren't accidentally updated to
  a new version when not intended.

This means that `gem install vcr --development` won't work
but I've never heard of anyone doing that. All VCR
contributors use bundler, anyway.
