Support jade files about cloc

Hmm just was reading GitHub.

Looks like it's now called pug, because of some trademark thing.

Please point me to a reference showing how pug comments are defined.

Here's how comments are handled. http://jade-lang.com/reference/comments/

Looks like they haven't set up new doc's yet with the new name yet.

Pretty much the same as javascript:

// this is a comment

but block comments are like support too:

//
  this
  is
  a
  comment too`

commit 6bbf37c adds support for Pug; please test it and let me know if it works as expected

[keverw]

I just gave it a quick test with this file:

//list
ul.lol
    li.foo=cow

//
    this
    is
    a
    block
    comment

and got this for the output

-------------------------------------------------------------------------------
Language                     files          blank        comment           code
-------------------------------------------------------------------------------
Pug                              1              1              7              2
-------------------------------------------------------------------------------

So it looks like it's counting correctly. Thanks :)
