* org-read-prop
** added a more detailed comment
** changed 2 if stements to 1 cond to make the code more comprehensible.
** added 
(condition-case nil
	(read prop)
	(error prop)))

instead of
(read prop)

so, if any error occurs during the conversion of prop to lisp expression - a string will be returned.

** The scheme of the new function if attached.
