Dfoxpowell/modal oform signin signup

- Implement oform on signup/signin modals
- move oform globals to global js because it was not getting included before it was called in modal component JS --- Need Browserify!!!
- log response from signup to segment
- styling for error classes in helpers and modal scss
@kylerush error event does not fire.  I add a custom function in the 'load' event that returns early if there is a status other than 200.
```
   if(e.target.status !== 200) {
      showOptionsError(optionsErrorElm, resp.error);
      return;
    }
```
Also, I added the body parser to the middleware so we can mock up error responses
