Current events have renewed the conversation in our community about the roles of terminology with racist connotations in our software. Many companies and developers are now taking appropriate steps to remove this terminology from their codebases and products. (e.g. [GitHub](https://twitter.com/natfriedman/status/1271253144442253312)) This small rule prevents the use of declarations that contain any of the terms: whitelist, blacklist, master, and slave. It may be appropriate to add more terms to this list now or in the future.
The MIT license doesn't require that all files be prepended with this
licensing or copyright information. Realm confirmed that they're ok with this
change. This will enable some companies to contribute to SwiftLint and the
date & authorship information will remain accessible via git source control.
