Benoît Minisini 9b46a269c7 [DEVELOPMENT ENVIRONMENT] 
* NEW: Adds a popup menu to the console window.

[WIKI CGI SCRIPT]
* BUG: Display a message when accessing a symbol page that does not exist 
  in the current version.

[EXAMPLES]
* NEW: New Barcode example made by Charles Guerin and modified by me.

[INTERPRETER]
* NEW: New API for returning the fully-qualified domain name.
* BUG: Fix a bug in DateAdd() that made this function corrupt the next 
  date to string conversion, which then lead to other bad weird things.

[GB.DRAW]
* BUG: Fix Draw.Circle center that was shifted one pixel to the top left.

[GB.GTK]
* BUG: Window.Reparent() now works correctly when embedding or unembedding 
  a top-level window.
  
[GB.NET.SMTP]
* NEW: Do not use MIME parts when it is useless.
* BUG: Try to use the fully-qualified domain name when sending the EHLO 
  command to the SMTP server. That actually works only if the system domain
  name has been set to the DNS domain name.

[GB.PCRE]
* BUG: Fix crashes due to bad uses of interpreter API.

[GB.QT]
* BUG: Fix the drawing of the frame of cached DrawingArea controls.
