Locked Pages apear locked

[Neeks]

Right now when you lock a page it is hard to tell if i is locked until you try to save/open a page.

• locked pages, could have a locked font-awesome icon next to them, or a different color.
• On page open in the Admin panel you could get a warning message:
  "This page is locked John Smith on 2/3/2014 5:30pm. Page can not be saved without being unlocked."

Justing brining this up here incase some of these features would benefit from being in the core. right now i'm trying to build a module that does some of what I mentioned above. If these features already exist and I just have not seen them yet, let me know.
