* This was originall called Timed KLines, but today it's

* but also by spamfilter etc...
* USAGE:
* This routine is used both internally by the ircd (to
* for example add local klines, zlines, etc) and over the
* network (glines, gzlines, spamfilter, etc).
* add: remove: spamfilter: spamfilter+TKLEXT sqline:
* parv[ 1]: + - +/- + +/-
* parv[ 2]: type type type type type
* parv[ 3]: user user target target hold
* parv[ 4]: host host action action host
