changed the algorithm how sessions work:

- if the IP is banned or there is no a winix function then we set a temporary session
- else
  if there is a session's cookie sent by the client then:
   - if the cookie is a correct session's cookie then we set the session from the cookie
   - or if the cookie is not a correct session's cookie (e.g. session expired) and the winix function
     requires a cookie then we set a new session
   - or if there is no cookie sent then if a winix function requires a session we create a new session

  if there was an error creating a new session or event counters reach a ban limit then a temporary session will be used
