        - ensured validation mode that causes trouble are not used
        There is a problem when using :validate :all or ':validate focus' in a
        entry or a spinbox.
        If the next action after the entry loosed focus is a click on a menu,
        and then on
        a menu button, the program freezes.
        This behaviour will not happen if validate is :focusout, though.

	* src/sanitize.lisp:

	Fixes issue 22 - sanitize mis-formats numbers
	The sanitize function converts numbers (actually, all non-strings,
	non-lists) to a string (using to-s) before they get to the format
	control string, and to-s uses the ~a directive. This means the control
	string provided to format-wish cannot use numeric directives.
	This fix adds a method to handle numbers by passing them back
	unchanged
	for formatting by the format-wish control string.
