Benoît Minisini 23dd0b0299 [DEVELOPMENT ENVIRONMENT]
* BUG: Do not search text inside form anymore.

[INTERPRETER]
* BUG: The startup class is not global anymore, so that it does not 
  conflict with anythign having the same name in components. The 
  interpreter API that was returning the startup class has been updated
  to reflect that change.
* BUG: File.Name("/a/b/") now returns a void string instead of returning 
  "b", to be coherent with File.Dir().

[GB.DESKTOP]
* NEW: Use the new API returning the startup class.

[GB.FORM]
* BUG: Setting DirView.Root with a path ending with a slash does not crash
  anymore.

[GB.GTK]
* NEW: Use the new API returning the startup class.

[GB.QT4]
* NEW: Use the new API returning the startup class.

[GB.SIGNAL]
* NEW: Use the new API returning the startup class.
