Create settings and preferences

In case i forget:

If we want settings to start at the beginning of the app: use this instead:

<activity android:name=".MyPreferenceClass"
              android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
</activity>
