[PATCH] Added button functionality for awful.widget.progressbar

[Ignas Anikevicius]

 Hi,

this is my first patch made for awesome and I wish it is well written 
and formatted and etc. If not, I am happy to hear and fix my mistakes.

So what basically I did was to add function to set widget buttons for 
awful.widget.proggressbar:

   * New function created (set_buttons)
   * Updated properties table (added "button_table" field)
   * Modified update() function to work with newly created property

I tested this and it works as expected.

Cheers,
Ignas Anikevicius
