I have changed `assert!(a == b)` calls to `assert_eq!(a, b)`, which give better error messages. Similarly for `assert!(a != b)` and `assert_ne!(a, b)`. Basically all instances were comparing primitives (string slices or integers), so there is no loss of generality from special-case macros, I have also fixed a number of typos in comments, variable names, and a few user-facing messages.
