Subject: Browser enhancements: (all) Only go back to the root dir after USB
 mode if the current dir no longer exists. (all) Use TREE_MENU as a quick
 alternative to leave a sub-browser. (recorders) Correct indication of
 available functions in the buttonbar. Indicate the new 'quick leave' method
 accordingly.
