Title: Improve version specification recommendation

Previous Gemfile recommendations for rubygem version were too strict.
This recommends the latest feature release version up to the latest version of
the gem.

This has the same behavior for when versions are < 1.0 or >= 1.0.
There was some debate about this in #409.

Fixes #409
