Make footer phone number clickable

[Tiggerito]

Wouldn't it make sense to make the phone number in the footer clickable, so users can directly make a call?

templates\components\common\footer.html

change:

<strong>{{lang 'footer.call_us' phone_number=settings.phone_number}}</strong>

to

<a href="tel:{{settings.phone_number}}"><strong>{{lang 'footer.call_us' phone_number=settings.phone_number}}</strong></a>
