Subject: * input.c (cook_keycode): properly handle LockMask

* input.h: added prototype for keysym_to_string

* input.c (keysym_to_string): added

* bar.c (show_bar): update_window_names(s) is called whether the
bar is raised or not.

* conf.h: Added BAR_Y_PADDING BAR_X_PADDING

* list.c (goto_window_name): return success or failure

* list.h: updated prototype for goto_window_name

* events.c (handle_key): Added a message indicating an unbound
key.

* bar.c (display_msg_in_bar): added
(update_window_names): uses BAR_X_PADDING instead of `5'
(update_window_names): Updated BAR_PADDING to BAR_Y_PADDING

* input.c (cook_keycode): mod is now an usigned int
(read_key): Ignores modifier keys. Now returns keysym and
modifiers.
(get_input): Updated BAR_PADDING to BAR_Y_PADDING and
BAR_X_PADDING.

* events.c (handle_key): uses read_key instead of XMaskEvent to
read a key.

* actions.c (goto_window_number): window list is displayed on failure.
(bye): added
(switch_to): added
(execute_command): no longer seg faults when no windows exist.
