#1 Allow to invert the priority/section

[Salvador Eduardo Tropea]

Is nice to be able to disable the priority and section
categorization, but I would like to invert them.
I know dselect doesn´t have it, but I think is better
if I can get:

DEB Packages
+Uninstalled
-+net
--+optional
--+extra
---etc

Optionally optional, extra, etc. could have different
colors as new have.
Or it could be in a column.
