Add support for international phone number format

I just realized that this is probably more complicated than I thought because the E.164 standard for international phone numbers can have country codes of variable length (for example +1 for the US and Canada, +49 for Germany, +233 for Ghana etc.). Also city codes vary a lot.

Google's libphonenumber could come to the rescue, but it's probably an overkill in most use cases (> 200kb minified code). But it might be an option that could be activated. More on the topic here.

Another way could be to define a format in the module settings (for example telling how to slice the numbers).

In my case, for a German phone number (+49) I just patched phoney.js in lines 89 and 90 to this:

element.setAttribute('href', 'tel:' + tel);
element.innerHTML = '(' + tel.slice(0,3) + ') ' + tel.slice(3,6) + '-' + tel.slice(6);

Not a solution, but a workaround to display a German number with a 3-digit mobile code like this: +49 123 4737628.

Hi @yan -

Perfect, glad you could extend it to meet your needs, (the beauty of open source).

I agree, the various international formats make it a minefield of issues that I really can't support.

I wrote the module for personal use but wanted to offer it to anybody with similar privacy concerns. However I don't really have the time/energy to support an international version and intentionally limited the scope. Plus, I'm really not much of a JavaScript coder.

Thank you for your time.
