fixed goto case dialog

The goto case dialog did not work. The GtkTreeModel cast of the datasheet
does not work because datasheet is not derived from treemodel. Changed
types from casenumber to gint because the gtktreemodel function returns gint.
casenumber is long which my be bigger than int but the treemodel cant handle
this anyway.
