[FIX] im_livechat: chat_window: scrollBottom() and feedback

The function scrollBottom has been removed at rev. 30c26d7 as the scroll logic
has been moved to the thread, to make it common for the client action and chat
windows.

Moreover, the o_chat_content div has been removed from the chat window layout
at the same commit, we thus now directly replace the thread's $el by the
feedback and fix less rules

Also adapt the behavior of the livechat's chat window as done for the backend
at 30c26d7:
  - scroll to bottom on message sent
  - increment unread messages counter if the chat window is folded or if the
    thread is not scrolled to bottom
  - reset the unread counter on scroll to bottom)
