Bug 1010127 - Show configred but no signal AP as 'Not in range'

Chuck, this implementation works nice but I think the order can be changed to make it more readable like this : 

```javascript 
      // security ap
      if (keys && keys.length) {
        icon.classList.add('secured');

        // and configured ap but not in range
        if (network.known && level === 0) {
          small.setAttribute('data-l10n-id', 'notInRange');
        } else {
          // not configured
          navigator.mozL10n.setAttributes(small, 'securedBy', {
            capabilities: keys.join(', ')
          });
        }
      } else {
        // open ap
        small.setAttribute('data-l10n-id', 'securityOpen');
      }
```
