[PATCH] org-get-cursor-date regexp patch

The regular expression in `org-get-cursor-date' assumes the time 
grid string will have two digits in the hour portion of the time 
strng.
However, the grid time string does not always have two digits. For 
example:

" 8:00......"

The attached patch accounts for this and uses the rx macro to 
communicate the intent of the regular expression more clearly.
