Updating cookies settings

SUST-40 – Eliminate unwanted problem_get ajax requests flooding the LMS.

An event is being fired on actions (Check/Save/Reset) to keep track of updated problems. On coming back to already visited sequence position, while putting sequence contents in container, only those problems that are found outdated, are going to be updated from earlier tracked problems.

[SUST-40]

The page visit requires an ajax request to get the notes. Without
waiting for that to complete, additional navigation results in a
socket error.

Example failure from the stub service:
```python
Traceback (most recent call last):
  File "/usr/lib/python2.7/SocketServer.py", line 295, in _handle_request_noblock
    self.process_request(request, client_address)
  File "/usr/lib/python2.7/SocketServer.py", line 321, in process_request
    self.finish_request(request, client_address)
  File "/usr/lib/python2.7/SocketServer.py", line 334, in finish_request
    self.RequestHandlerClass(request, client_address, self)
  File "/usr/lib/python2.7/SocketServer.py", line 657, in __init__
    self.finish()
  File "/usr/lib/python2.7/SocketServer.py", line 716, in finish
    self.wfile.close()
  File "/usr/lib/python2.7/socket.py", line 283, in close
    self.flush()
  File "/usr/lib/python2.7/socket.py", line 307, in flush
    self._sock.sendall(view[write_offset:write_offset+buffer_size])
