Benoît Minisini 53c284099b [DEVELOPMENT ENVIRONMENT] 
* BUG: The name of GridView controls is now always visible in the form
  editor.

[INTERPRETER]
* NEW: Support for new QUIT syntax.
* NEW: Do not display overriding prefix in class names.

[COMPILER]
* NEW: QUIT now can takes an optional argument which is the program return 
  value.

[GB.ARGS]
* BUG: The "--version" option is not "----version" anymore
* NEW: If an error occurs, returns 1 as exit value and not 0.

[GB.FORM]
* BUG: GridView is correctly updated now when the Border property is set.
