Build and publish fix

Scripts made cross-platform, ensured dist folder should not forget to publish to npm

allow installation of the same build

If you run the tool with the --install option, the release with specified number is installed, even if it is currently installed already.

use "path" instead of "pretty_path"

CircleCI changed the API response and "pretty_path" property is no longer that pretty... So replacing that with use of "path" property while preserving backward compatibility as much as possible.
