this is not difficult to implement in the output plugin. But more
interestingly is where you want to store the gen_id? I think you
need an extra column in the signature table.
Or you can do the hack we've done with FLoP, if sig_generator is not
equal to GENERATOR_SNORT_ENGINE we insert the sig_generator as the
revision number of the rule. These numbers are > 100 and I don't
expect that any rule ever will get such a revision number.
In principle pre-processor alerts should be identifiable by the
sig_sid which should be less than 100. But there are several ones
which are bigger. Therefore we used this hack...
