Browsing Catalan (Valencian) translation

Translators: the 'flat review' feature of Orca allows the blind user to
explore the text in a window in a 2D fashion.  That is, Orca treats all
the text from all objects in a window (e.g., buttons, labels, etc.) as a
sequence of words in a sequence of lines.  The flat review feature allows
the user to explore this text by the {previous,next} {line,word,character}.
Next will go forwards in the window until you reach the end (i.e., it
will wrap across lines if necessary).
