Summary:
- Updates to SwiftLint 0.24.2
- Improve `scripts/lint.sh`
- pull version out to a var for easier maintenance
- better error message
- make script fail xcode build if not installed (so we don't commit lint errors)
- Adds a few new SwiftLint rules
- Correct all new lint errors (most can be done by running `swiftlint autocorrect`)
- Cleans up `.swiftlint.yml`
- Fix up example projects
Closes https://github.com/Instagram/IGListKit/pull/1058
