Enhancement Bug #2002 is titled "Add ability to make any field a column"

  http://bugs.wireshark.org/bugzilla/show_bug.cgi?id=2002

I am very interested in getting this implemented as well, but have not
had the time to do it yet.  I was thinking that this could be
implemented using the proto_tree_add_* functions.  Those functions would
check if a column with the contents of the field being processed is
active and if so, populate it.  I am not sure how much of a performance
hit we would take doing this though.
