rockbox/apps/root_menu.c
Jonathan Gordon efbcece07b New setting to control the file browser start location.
Set using the menu item in folder context menus, clear in the filebrowser settings.
    
    Can be abused to start selecting a *file* (or have a folder selected) instead of a starting inside a folder by removing the trailing / in the .cfg
    
    This only affects the file browser when it would open in / before (on boot, or when entereing after backing out of the browser before (*not* when exited with the menu action)
