Not planned Invoice Menu Icon

[PASS]

Not sure the best place to post this. This is just to help others add a menu icon for the Invoices link if they are using [cXF] Icons in Visitor menu DYI.

Just have to add this to his CSS in the extra.less template. You can choose any font awesome icon you want.

&[href*="user-upgrade-invoice"]:before {
.m-faContent(@fa-var-file-invoice);
}
