@hkrishna , @dianashk , @missinglink , did this merit more discussion before getting merged? I can revert so that we get a chance to collectively look it over.

[question] @sevko @hkrishna will this add a 3kb payload to each db query containing ./helper/category_weights.js? That sounds not ideal...

[sevko]

Currently, yes, and no, it isn't. Could either move those into the Groovy scripts, but that stops us from injecting and thus easily configuring them. Since they're virtually all currently set to 10, which serves as a default value, we can just remove anything that doesn't have a non-default weight (ie, in the Groovy script, assume a weight of 1 unless a custom weight for the given category was present in the injected weights object).

OK that sounds better, thanks.
