/**
* An {@link EditTextPreference} that uses the default dialog theme of the platform.
*
* <p>This is necessary because KouChat is using a light theme from ActionBarSherlock,
* but the theme doesn't apply correctly to dialogs on Android 2.3.3. The dialogs in that version
* are still dark, but the text changes to a dark color. So it's difficult to read.</p>
