Always display collapsible content

Currently on notalone.gov if a user opens a second collapsible content area the window jumps to the middle of the content.

The screenshot below displays what a user sees if they visit the Students page, click "How Do I File a Complaint About My School? And Then What Happens?" followed by "Will What I Share Remain Confidential?"

This is a quick fix that calculates the position of the clicked heading and scrolls to that position when a content area is expanded:

```javascript
last_scrollTop = $(this).position().top;
$(window).scrollTop(last_scrollTop);
```
