Benoît Minisini bdd864f41a [DEVELOPMENT ENVIRONMENT]
* BUG: Fix windows using icons not existing anymore.
* NEW: Add dark theme versions of some icons.

[INTERPRETER]
* NEW: "../xxx" now refers to a file located in the parent archive, not
  necessarily the main project archive. "../../xxx" refers to the 
  grand-parent archive, and so on. A component written in Gambas that 
  receives a relative path is supposed to prefix it with "../" if he wants 
  to access it. Please report any incompatibility!
* NEW: File.IsRelative() is a new method that returns if a file is 
  relative, i.e. if it does not starts with '/' or '~'.
  
[GB.FORM]
* NEW: The Stock class does not use the Picture cache anymore. It is 
  useless as normally the Stock class is accessed from the Picture[]
  method.

[GB.FORM.MDI]
* BUG: When browsing actions, do not try to load an icon for actions that
  do not have one.

[GB.GTK]
* NEW: Remove the Picture[] array accessor and the Picture.Flush() method.
  They are now implemented in the 'gb.gui.base' component.
  
[GB.GTK3]
* NEW: Remove the Picture[] array accessor and the Picture.Flush() method.
  They are now implemented in the 'gb.gui.base' component.
  
[GB.GUI.BASE]
* NEW: The Picture[] array accessor and the Picture.Flush() method are now 
  implemented in that component.
* NEW: Remove support for theme specific icons.
* NEW: Add support for right-to-left specific icons. For example, if an
  icon is named 'abc-ltr.png', then it will be considered as a 
  'left-to-right' icon, and the 'abc-rtl.png' icon will be used if the 
  current langauge is right-to-left written.
* NEW: Add support for dark theme specific icons. An icon named 
  'abc-dark.png' will be the dark theme version of the 'abc.png' icon.

[GB.QT4]
* NEW: Remove the Picture[] array accessor and the Picture.Flush() method.
  They are now implemented in the 'gb.gui.base' component.
* NEW: Message boxes do not support theme specific icons automatically 
  anymore.
  
[GB.QT5]
* NEW: Remove the Picture[] array accessor and the Picture.Flush() method.
  They are now implemented in the 'gb.gui.base' component.
* NEW: Message boxes do not support theme specific icons automatically 
  anymore.
