/**
 * PreferenceCategory fix which allows one to use multiple themes. The original
 * "preference_fallback_accent_color" override would not allow this as it is not modifiable during
 * runtime.
 * If you use this class in your preference XML, you don't have to redefine
 * "preference_fallback_accent_color".
