even yet still more cool SimpleList features

[muppet <scott asofyet org>]

tonight i added support for editable columns and index-based selection 
handling in Gtk2::SimpleList.


This makes it possible to do things like

  # create a list which we'll use as a table, keys in col 0, values in 
col 1
  $list = Gtk2::SimpleList->new (qw/Glib::String Glib::String/);

  # allow the user to change the string values to taste
  $list->set_column_editable (1, TRUE);

and

  $dlg = Gtk2::Dialog->new (...);
  ...
  $list = Gtk2::SimpleList->new ('Glib::String');
  # set the TreeView to multi-sel through the normal methods
  $list->get_selection->set_mode ('multiple');
  $list->set_reorderable (TRUE);
  # set some list data...
  @{ $list->{data} } = @bunches_of_things;
  ...
  $dlg->run;
    # here the user can muck with the selection
  ...
  # now find out which rows are selected
  @selinds = $list->get_selected_indices;
  # grab the corresponding items in a slice from the
  # list data --- note that we use the actual list data,
  # because it will reflect the order, no matter how
  # much the user reordered it!
  @selected_things = @{ $list->{data} }[ @selinds ];

i don't know about you, but i'm really excited about that second 
example!  that's a *lot* of power for very little work!

SimpleList will be in 0.92, slated for release this friday.  if you 
can't wait 'til then to try it out and sourceforge CVS doesn't show the 
lastest changes, email me offlist and i'll send you a copy.  we're very 
anxious for bug reports and feedback on this.
