Common: Gui version constants
Common: GUIF_TRANSLATED flag for certain GUI controls

GUIF_TRANSLATED flag tells engine whether to apply translation to the control's text.
This only works for Buttons, Labels and ListBoxes.
For this version of the engine, all buttons and labels are forced to have this flag set. List boxes read the flag from the game data file. All games before 3.3.0.1132 have this flag cleared, therefore list boxes will NEVER be translated for older games.
Editor: New 'Translated' property for ListBox gui control

Defaults to 'true' in new projects created with AGS 3.3.0.
Defaults to 'false' in imported projects created with AGS < 3.3.0.
