update-ipsets handles everything.

We are about to release firehol v3
The master branch is stable too.
I use it on production machines. Since firehol and update-ipsets are
just scripts, there are very little to go wrong. Even if something is
wrong and we don't know it yet, a specific feature or function will
most probably fail. You can use the 'explain' mode of firehol to check
the generated iptables statements, in order to trust it.
