added dependency on Zenity remove error_on_generic_command() and

	* configure.in: added dependency on Zenity
	* src/core/keybindings.c: remove error_on_generic_command() and
	  error_on_terminal_command(); rewrite error_on_command
	  in terms of meta_show_dialog()
	* src/core/util.c: add meta_show_dialog() to call Zenity
	* src/include/util.h: ditto
