New keybindings code and backend. New structs subnfunc for menu functions 

and toggles and sc for shortcut keys, old 'shortcut' and 'toggles' structs are
gone.  The current implementation has a bunch of broken stuff (some of which is
documented in BUGS).  Updated nanorc.5 with some mostly complete documentation
on configuring.
