Clean up lint errors
Created by: tbenz9
If anyone is looking to contribute, some easy, beginner level tasks would involve adding more packages (one at a time please) to our $lintpkgs in our Makefile and cleaning up all of the linting errors That's a good way to learn go if you aren't familiar, and it's something that would benefit the project.
