DONE header argument values are not being collected from properties

Many types of header arguments are not having their values properly read from outline-level properties.

There were two problems here

  1. we weren't searching for all needed header arguments in properties
  2. we weren't inheriting header arguments from enclosing properties

both of these issues were resolved in changes to org-babel-params-from-properties (see below).

  1. we are now tracking the following properties 
    '("cache" "cmdline" "exports" "file" "noweb" "results"
               "session" "tangle" "var")
  2. we now search the properties of enclosing headlines by adding t as the last argument to 
    (org-entry-get (point) header-arg t)

code for `org-babel-params-from-properties' 

(defun org-babel-params-from-properties ()
  "Return an association list of any source block params which
may be specified in the properties of the current outline entry."
  (save-match-data
    (delq nil
          (mapcar
           (lambda (header-arg)
             (let ((val (or (condition-case nil
                                (org-entry-get (point) header-arg t)
                              (error nil))
                            (cdr (assoc header-arg org-file-properties)))))
               (when val
                 ;; (message "prop %s=%s" header-arg val) ;; debugging
                 (cons (intern (concat ":" header-arg)) val))))
           '("cache" "cmdline" "exports" "file" "noweb" "results"
             "session" "tangle" "var")))))
