o Modified example to take advantage of new Fl_Table::tab_cell_nav() method

Browse Source 
o Changed behavior of example to be more predictable
o Enter key can be used to toggle edit mode
o User can navigate table cells with arrow keys or tab/shift-tab without slipping into cell edit mode
o Fixed other issues with Alt, Shift, multicell selection..
