Replace VU meter menu with a new one using the new menu api, fixes some

problems:
* Up/Down buttons are no longer reversed.
* The menu looks much better with reversed bg/fg colors instead of 
inversed.
* Menu uses userfont.

Add the set_bool_options function to the plugin api and bump api 
version.
