Adds support for Republic of Ireland phone number formatting

[stevenyan]

Initial support for Republic of Ireland number formatting.

Irish NDCs are 2-3 digits in length, and the subscriber number length varies from 5-7 characters.

7 digit subscriber numbers are split 3-4.
5 and 6 digit subscriber numbers are not currently split, though I have seen some examples of splitting, it's inconsistent.

In the event that an NDC is not recognized, the NDC and subscriber number will not be split at all, e.g. +3530001234567 will be formatted as "+353 0001234567" so as to not assume a split.

Fantastic, Steven, fantastic! :)

Many thanks for adding the Republic of Ireland to Phony's capabilities and for the explanations.

I will read, pull and release tomorrow. Thanks again!

I've just released 1.6.3 with your generous donation of Ireland! :) Please also see https://github.com/floere/phony/wiki/Contributors.

Note: I've had to change a spec regarding VoIP – I saw it was under the list with a 5-digit subscriber number and changed the spec accordingly. If this is wrong, please tell me.

You're absolutely right, I think I was reordering some of the code and placed that in the wrong section. Thanks for catching that.

We use phony at Zendesk to handle number formatting for our Voice product: http://www.zendesk.com/product/features/voice. Thanks for providing this gem!

My pleasure! Is it ok to add zendesk to the list of users in the README?

Sorry Florian, I misunderstood you. +353 76 belongs to the list of 7-digit subscriber numbers, our Voice product allows provisioning of these and I know it's a 7 digit number. If you search online you can find other examples like on this page:

Yes, feel free to add Zendesk!

Thanks!

Ok, I'll move it to the 7 digits list then and release again :)
