patch: clearing keymaps && segfault in conf-bindings.c

[ingok]

hi,

here is a patch that enables to clear a key map by assigning an
empty table.  works for me.  (well, one can hack a vi key binding
for the wedln with it :)

overloading the binding function that way is clearly ugly
(not to mention creating key maps every time you switch vi mode).

but as a vi addict and ion code ignorant so far i had no choice ...

ingo

ahm, there is one serious item, though, currently process_bindings()
segfaults on an empty table.
