`localeapp cp` has landed!

Hi everyone,

We just released a new version of the `localeapp` gem that introduces a most expected feature:

localeapp cp <source key> <destination key>

As you may have guessed, it lets you copy a translation. If the destination key already exists, it will be overwritten (except if it is a namespace, for obvious data safety reasons).

We hope you will enjoy it: simply upgrade to `localeapp` gem version 3.1.0.

Happy translating 🌐
