Implement a filter for a telephone number

[jniles]

There are a few places we need to display telephone numbers in the application (receipts, reports, lists of users, etc). A handy component to have would be a telephone filter. Something that could be easily embedded in a view such as this:

<span>{{ patient.telephone | telephone }}</span>

... to yield a nicely formatted telephone number (e.g. +243 821 453 233).

How the system will know about the code, we will deal with locale.js (_locale.js is the right name ?_)? because each country has is own code for telephone number.

This filter would only use information provided by the user. So, if the user writes "0821238945", it would render 082 123 8945, instead of trying to guess the country code.

... if we wanted to get all the information possible, on the telephone <input type="telephone"> we might put a drop down for every country code, preloaded into the application. But I think it is too much work for little benefit at the moment. It's a good idea though! Maybe we can plan it as a long-term feature to add polish.
