To prevent heigth change on filtering.

We now list all available IPSets and Aliases.

We can only delete empty groups, so that is not necessary.

And use a hidden field to forms with errors as dirty.

and do not use pvetextfield/deleteEmpty, because that is no longer
necessary with recent firewall API changes.

And use pvetextfield instead of textfield to correctly handle 'delete' parameter.

for readability, better to have

macro
proto
src port
dest port

in same column
