Title: allow to use both --locale and --version params for 'wp core download'

(First contribute ever on Github, please be carefull in merging)
Ugly coded, but not so different from source. If the requested combination of locale+version is not available, the script fails like with wrong version parameter.
Tested setting it_IT and de_DE parameters and various versions.
