Better indication a topic is locked

[strager (Scott Trager)]

So I was perusing the Emby forums the other day and I came across a locked thread. It was very obvious that the thread was locked because instead of the Post Reply button there was a big giant “This Topic is Locked” icon in it’s place. Just wanted to suggest that Discourse consider doing something similar - this is really helpful as an end user so you aren’t spending any time trying to reply to something when you don’t realize it is locked.
