[angularjs] How to use <md-icon> in Angular Material?

All md- prefixes are now mat- prefixes as of time of writing this!

Put this in your html head:

<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">

Import in our module:

import { MatIconModule } from '@angular/material';

Use in your code:

<mat-icon>face</mat-icon>
