Remove shoulda cuke.

- It doesn't give us any test value, really; it was
  just there for the documentation.
- I've never heard a single report of any VCR users
  using shoulda, so I'm not convinced we need the cuke.
- It's fairly obvious how to integrate VCR w/ shoulda.
- Upgrading should pulled in active support 4.0, which
  won't install on < 1.9.3, so to keep building against
  older versions of ruby it's best to drop the shoulda
  duke and dependency.
Don't unnecessarily load bundler in rakefile.

This allows --standalone to be used instead.
Update typhoes_old gem file.
