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)
