Changing the input value on color change #174

First Thank you for this color picker,
When I added this line into my project:
<input type='text' data-coloris= />

I needed the value when client chooses a color, so I added this line to update input value,
now you can get the value from input:
<input type='text' id='client_color' value='#00ff00' data-coloris= />

this value will update whenever client change the color.

src/coloris.js [line 493]

Thanks again.
