Title: remove Ruby version clamping for collins-shell

The version check prevents collins-shell from running on Ruby 2.x,
even though it works just fine.

Instead of "fixing" the check, just remove it wholesale, on the premise
that anyone who is still using Ruby 1.8 or 1.9.1 has it coming, and all newer
versions should be supported.
