Bad Accessibility: the title for the Like button should vary according to its current state

[mesosoi]

Currently the button has a title of "Click to like or unlike this post". It would be much better to use different titles according to the current state:

• If likes are not disabled, and the post is liked: "Click to unlike this post"
• If likes are not disabled, and the post isn't liked: "Click to like this post"
• If likes are disabled, and the post is liked: "You have liked this post and you are not able to remove your like"
• If likes are disabled, and the post is not liked: "You have not liked this post and you are not able to"
