/** Notify the http logon server from the various step that have been reached in the client.

  * - how many player manage to do a successful video driver initialization ?
  * - how many player did pass the login screen ?
  * - what is the mean loading time from character selection until in game ?
  * - etc.
  * The sending is done in a separate thread to avoid freeze of the client (especially at launch
