Adam Leff 4b9acb4800 Bump Rubocop to 0.49.1 (#2323)
* 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.

* Set end-of-line format to line-feed only, avoid Windows-related CRLF issues
