Steve Howell eb1344c41c list_render: Fix filtering/sorting. ...

This code has always been kind of convoluted
and buggy, starting with the first
sorting-related commit, which put filtering
before sorting for some reason:

    3706e2c6ba

This should fix bugs like the fact that
changing filter text would not respect
reversed sorts.

Now the scheme is simple:

    - external UI actions set `meta` values like
      filter_value, reverse_mode, and
      sorting_function, as needed, through
      simple setters

    - use `hard_redraw` to do a redraw and
      trigger external actions

    - all filtering/sorting/reverse logic on
      the *data* happens in a single, simple
      function called `filter_and_sort`
