* This activity allows users to modify the settings for the search activity.

* A note on implementation: At the moment, we don't have tablet-specific designs.
* Therefore, this implementation uses the old-style PreferenceActivity. When
* we start optimizing for tablets, we can migrate to Fennec's PreferenceFragment
* implementation.
*
* TODO: Change this to PreferenceFragment when we stop supporting devices older than SDK 11.
