Properly adds a readmore link on long items.

Sidenote — here’s some code I used previously when I was trying to do this without duplicating text in .teaser:

<article class="legislation" id="matter-{{matterId}}"

.legislation.shrunk {
	.teaser::after {
    	content: '\2026'; //ellipsis
    }
    a.readmore {
    	display: inline-block;
    }
    .remainder {
    	display: none;
    }
}


// // '→ Continue Reading' link
// var lastPara = $('#matter-' + item.EventItemMatterId + ' .body p:last-child');
// var continueReading = '<a href="#" class="readmore"> &rarr; Continue Reading </a>';
// lastPara.html(lastPara.html() + continueReading);
