Fix Force Close of Recent long press options in settings
- When Long press actions (navbar_long_press_actions.xml) is clicked first the settings look for android:key="recent_long_press" but as i'm stupid i did not rename it in NavBarLongPressActions.java
This commit fix this little derp and also finally rename the remain to RECENT and not RECENTS.
