Fixed follow / following start icon title

Btw, I find it kinda confusing we have different definitions for the same purprose so it seems;

$definitions["Starred"] = "Following";
$definitions["Following"] = "Following";

---
also:
$definitions["Unstarred"] = "Not following";
$definitions["Follow"] = "Follow";

But not:
$definitions["Star"] = "Follow";
$definitions["Unfollow"] = "Not following";
