Fix the installation of cli.

[michelts]

Hello, @cheton

I'm trying to install the latest release of i18next-scanner without success:

$ npm install i18next-scanner
...
npm ERR! enoent ENOENT: no such file or directory, chmod '/tmp/container/node_modules/i18next-scanner/bin/cli.js'
npm ERR! enoent ENOENT: no such file or directory, chmod '/tmp/container/node_modules/i18next-scanner/bin/cli.js'
npm ERR! enoent This is most likely not a problem with npm itself
npm ERR! enoent and is related to npm not being able to find a file.
npm ERR! enoent 

I could install it if I ignore the bin links:

$ npm install i18next-scanner --no-bin-links

I think you miss the bin folder to be added to the package :)

I added it but I don't know if we need to test it, or how to test it. Do you have any suggestion?

Coverage remained the same at 91.877% when pulling fca8be1 on michelts:fix-cli-installation into f81bd6d on i18next:master.

Arrgh. I forgot adding "bin" to the files. Thank you for the PR.

[michelts]

No problem :)

Thank you for the quick response!
