Strong support for removing moment.js. Some context that I think might be helpful: 

- I originally addeded moment.js for two features: timezone support (native JS only handles timezone support for the user's local timezone) and relative times (ie: 2 days ago) 
- Relative time can probably be replaced with a single ~100-200 line function, but there's a lot of cases to test for, which makes it kind of annoying. 
- The only timezone besides the user's timezone we really need is Pacific time, for timestamps that we want consistently displayed in MTV time. 
- chops-timestamp also uses moment.js, which we should definitely replace. This could be how we share a home-grown relative time library.
