Base: Speeding up ad-list

[Siamesecat]

This is probably irrelevant to what is being discussed here, but I improved the ad filtering speed of the Banner Blaster filter from Scott's default.cfg file by putting the keywords back into the filter and removing the reference to any external list. Since anchors are still the most common type of ads, and there can be many of them on a page, I found that the filter jumping first to the keyword list and from there into the ad host name list took too long, and slowed down page loading.
