NEWT/X11 Display: CloseDisplay in same order as creation (ATI); Adding DisplayRelease0; Using 'EDT' suffix for display arguments

CloseDisplay in same order as creation (ATI)
  - This enhanced the erroneous bug 515 (b54497155815852744adb657816cb4057948dae2) situation
    with closing the display connections. However, some SIGSEGV still slipped through.

Adding DisplayRelease0
  - Intended for cleaning up resources. Currently a NOP.

Using 'EDT' suffix for display arguments
  - To mark the semantics of the display connection, which may be for window or EDT now.
