glyphicon-euro incorrectly named

Created by: hpoom

Seeing as glyphicon-usd and glyphicon-gbp use the ISO 4217 standard I believe glyphicon-euro should be changed to glyphicon-eur to confirm with this standard. This would make templating from a REST API that returns ISO 4217 code a lot simpler.

My code currently is: <span class="glyphicon {@eq key="{meta.currency}" value="EUR"}glyphicon-euro{:else}glyphicon-{meta.currency}{/eq}"></span>
