Write dev docs to clarify difference between blacklists and generation pipeline

[ghost]

Are the blacklists the urls removed from the respective blockers? Are they directly used in BarBock?

[paulgb]

blacklist.yaml is the master domain list that is blacklisted across all blockers/browsers. The URLs in barbblock.js are generated from the master list, as are the domains in the blacklists. The difference between the blacklists is just the format that they use.
