prune defunct blacklists from qtp-set-rbls

[hakamadare]

Several of the blacklists installed by qtp-set-rbls are arguably defunct; while nothing should prevent an admin from monitoring the health of the blacklists used by his own systems, it seems like it would be better if a qtp tool didn't make it easier for newbies to configure broken RBLs :)

Problem RBLs:

• list.dsbl.org (-loose, -moderate, -tight)

has been dead since 2008, per  http://dsbl.org/

• dnsbl.tqmcube.com (-tight)

homepage now points to a different for-pay blacklist, also see  http://www.dnsbl.com/2007/06/status-of-dnsbltqmcubecom-abandoned.html

• bl.csma.biz (-tight)

homepage currently gives 404, doesn't respond to DNS requests (this may be a temporary problem, unlike the two listed above)

Please consider removing these RBLs from qtp in a future release.

All of your changes have been applied. I also added a few rbls from Sam @spamdyke.org to the tight configuration.
