Cleanup: WebSocket Helper

File: websock.js
Tests Added: True
Changes:
- Cleaned up JSHint errors
- Converted to normal JS constructor pattern with "private" fields and
  methods now simply being prepended by underscores
- Added a "bind" polyfill for use in PhantomJS 1.x in util.js
- Added FakeWebSocket to fill in for actual WebSocket objects when
  testing
- Made exception handler actually log exception name and message,
  to console, in addition to stack trace
