[MdTabs] - Font Awesome support in components that uses the md-icon property #1843
Description
Font Awesome is supported by Vue Material when using it with md-icon and specifying the Font Awesome classes. However, components using md-icon as a property will not display Font Awesome icons, for example the md-tab component.
A proposal to support this is to either add a fa-icon property that specifically take Font Awesome classes as value, or to add a new v-else-if check at line 21 in MdTabs.vue that checks for Font Awesome class names in md-icon prop with a regex...
/^(fa[rsl]?\s)|(fa-)/g
...and then render Font Awesome icon with md-icon prop as class name if regex matches.
Also if other components use the md-icon property, do the same thing there.
