org-clock-time% does not parse "1d 12:50". This is a fix. (org-mode 8.1.1)

[Pierre-Henry Frohring <frohring.pierrehenry@gmail.com>]

Dear all,

While I was experimenting with clock tables

  #+BEGIN: clocktable :maxlevel 2 :scope file :formula %

I found a surprising result : if *total time* is formatted as "1d 12:50" then
the percentages column gives wrong results.  

The reason is that org-clock-time% does not take "1d 12:50" format into account
but only "12:50" format.

You will find my fix of org-clock-time% below.


Thank you.
