[pmg-devel] [PATCH pmg-gui v3 1/3] rules: use tree panel instead of grouping feature of the grid

[Dominik Csapak]

just in preparation for adding a column for the groups
will look similar (though not identical) to before, but this makes
the groups now real entries in the grid, which means we can have
content in additional columns
