Create Ireland-local-mobile

Ireland all area codes and mobiles
Can you look at the [Amsterdam](https://github.com/2600hz/kazoo/blob/master/applications/crossbar/doc/internationalization/examples/dialplan/NL_Amsterdam.md) file and update this file to use Markdown to look similar. Also, rename it to "IE_local_mobile.md" so parsers know it is Markdown.

Lastly, most dialplans convert to E164 (with a preceding '+'). Is that not necessary in Ireland? For instance, the US Embassy in Ireland lists its number as `+353 1 668-8777`.
