Version 3.5.12
Fixed a minor bug with Login screen & countdown timer...
Adjusted how countdown timers are placed and called. Functions affected:
  Timeout_Timer(), Login_response(), Countdown(), Start_Countdown(), and some
  misc code at end of file.
Added $LOGIN_DELAYED global due to above.
Countdown(): Added countdown to the 2-minute "Warning!" message box.
Improved Display_Messages()
Added a few php global variables for values that were otherwise hardcoded in js.
  These variables are declared in System_Setup():
  $DELAY_Expired_Reload, $DELAY_Sort_and_Show_msgs, $DELAY_Timeout_Timer, $DELAY_final_messages
Some minor readme updates.
