Episode of care measure icon size increase.

This increases the size of the episode of care measure icon size. @noranda is there a chance you could take a look at this and let me know if it matches what you were going for?
I'd recommend something like:
```css
.measure-type {
  .fa { /* ... */ }
  .glyphicon { /* ... */ }
}
```
if we need different rules for different types. That way you don't need to apply multiple rules for one type or another, and what you're trying to do will be more explicit.
