Feature js hint clean

refs #77 

Cleaned up most jshint problems. 

2 that remain:

    1. Peer-integration's peerSpec (in rewrite) calls removed code, left that issue untouched with a `TODO`.
    2. Eval on  [test/MockParticipant/init.js line:17](https://github.com/ozone-development/ozp-iwc/blob/86ef2b9fb9c191e3bcce1b745aa4bc412dcbb558/test/mockParticipant/init.js#L17) (can turn off the warning)
