Clocktable: Put summary line as table caption

["Sebastien Vauban" <wxhgmqzgwmuf-geNee64TY+gS+FvcfC7Uqw@public.gmane.org>]

Hello,

Looking at the presentation of the clocktable, I find that its "summary" line
should be converted into a caption, as any legend would be for any regular
table.

You can test it, and see its effect, with such a ECM file:

--8<---------------cut here---------------start------------->8---
* Development
  :LOGBOOK:
  CLOCK: [2012-09-28 Fri 10:00]--[2012-09-28 Fri 11:00] =>  1:00
  :END:

** Task 1
   :LOGBOOK:
   CLOCK: [2012-09-28 Fri 11:00]--[2012-09-28 Fri 12:00] =>  1:00
   :END:

** Task 2

*** Task 2a
    :LOGBOOK:
    CLOCK: [2012-09-28 Fri 12:00]--[2012-09-28 Fri 13:00] =>  1:00
    :END:

*** Task 2b
    :LOGBOOK:
    CLOCK: [2012-09-28 Fri 13:00]--[2012-09-28 Fri 14:00] =>  1:00
    :END:

* Clock tables

#+BEGIN: clocktable :maxlevel 1 :scope file
#+CAPTION: Clock summary at [2012-10-01 Mon 23:18]

| Headline    | Time |
|-------------+------|
| Total time  | 4:00 |
|-------------+------|
| Development | 4:00 |
#+END:
--8<---------------cut here---------------end--------------->8---

The following patch does it...
