[PATCH] tree.py: Fix treeview_search_cb() argument mismatch

[Peter Tyser <ptyser gmail com>]

When trying to find a file in dirdiff or vcview mode the following
error would be displayed:
  TypeError: treeview_search_cb() takes exactly 5 arguments (6 given)

Add an unused "data" argument to treeview_search_cb() to silence the
warning and allow file searching to work.
