ob-core: Display type of element babel executes

* lisp/ob-core.el (org-babel-execute-src-block): The babel execute
function is run on more than just source blocks, so it makes sense to
note the type of element being executed.  A fourth optional argument is
added to allow for explicit specification of the type of element
responsible for the execution.

* lisp/ob-lob.el (org-babel-lob-execute-maybe): Pass the type of the
execution triggering element to `org-babel-execute-src-block'.

* lisp/org.el (org-ctrl-c-ctrl-c): When executing a babel call, pass the
type of the execution triggering element to
`org-babel-execute-src-block'.
