Right now, we have some automatic reductions in accuracy depending on the size of a signature. We do this by using a faster, but less accurate algorithm. The result is that we maintain performance, but large signatures basically get randomly placed with large categories.

To fix this, I'm proposing that we also increase the default similarity threshold at each step of the size escalation. Default of 0.5 gets turned into 0.75 for quick, and 0.86 for really_quick.

To make sure we're not making things worse, I'd like to have the category efficacy issue completed first.
