Add support for el_bind_key() and example usage binding '?' in examples/cli.c

Browse Source 
This changeset refactors el_bind_key_in_metamap() into two functions,
adding el_bind_key(), to provide the ability for the user to bind keys
in both the regular and the meta-key maps.

Several useful, but previously internal, functions have been made global to
facilitate the example code mentioned above. These are likely useful to the
user of this library as well:

  el_print_columns() - Display words in columns across a tty_cols wide screen.
  el_ring_bell()     - Can be used as default key binding function.
  el_find_word()     - Returns a copy of the word at rl_point.
