[gtkmm/spread-table] ComboBox: Added get_entry() and get_entry_text().

[Murray Cumming <murrayc src gnome org>]

commit 18f0632f408ea86da7cc93b1a1814e89986902b6
Author: Murray Cumming <murrayc murrayc com>
Date:   Thu Oct 14 13:35:50 2010 +0200

    ComboBox: Added get_entry() and get_entry_text().
    
    * gtk/src/combobox.[hg|ccg]: Added our custom get_entry() method that was
      previously in ComboBoxEntry. It avoids the need to call get_child() and
      dynamic_cast<>. Added get_entry_text(), wrappping get_active_text(), which
      was previously only in ComboBoxEntry.
