* Bump Rubocop to 0.49.1 This change bumps Rubocop to 0.49.1. There have been a lot of changes since 0.39.0 and this PR is hopefully a nice compromise of turning off certain cops and updating our codebase to take advantage of new Ruby 2.3 methods and operators. Signed-off-by: Adam Leff <adam@leff.co> * Set end-of-line format to line-feed only, avoid Windows-related CRLF issues Signed-off-by: Adam Leff <adam@leff.co>
