Fixed bad endpoint names (sorry) and some cleanup

[jeffling]

• removed https module... wasn't used
• changed lead_status and opportunity_status to status.lead and status.opportunity respectively to fit in the rest of the API (ie. activity.note) and reflect the actual URL path
• added .jshintrc with airbnb/javascript settings, then fixed all but two errors (they want us to use camel case for everything, i didn't want to break the existing API)
• added an assert to the lead creation/update/delete test

Also - How come we can't make issues? Would be nice to be able to talk to you guys :)
