* Expand the linters and types of warnings to improve consistency and safety * Fail lint workflow if there are errors * golint has been replaced by revive * Hand-pick some of the default exclude list * Ignore error when trying to delete preview gif * Ignore linter warning opening playlist path * Rename user field Id -> ID * A bunch of renames to address linter warnings * Rename ChatClient -> Client per linter suggestion best practice * Rename ChatServer -> Server per linter suggestion best practice * More linter warning fixes * Add missing comments to all exported functions and properties
