Jqueryui dependency version modification

Hi 
   I have merged with the latest files from https://github.com/vanderlee/colorpicker/.

  Everything worked except images/ui-colorpicker.png is not loaded since in html source is like 
<img src="images/ui-colorpicker.png" alt="Color" title="Color" style="background-color: rgb(209, 121, 25);">
  
     I have attached the image. Could you please check it and merge?

Steps I did with ur gem and this patched version is 
1. Added //= require jquery-colorpicker  to application.js
2. Added *= require jquery.colorpicker   to application.js
3. Then 
   $(document).on "ready page:load", ->
  if $('#input_text').length > 0
    $('#input_text').colorpicker
      parts: 'full'
      alpha: true
      showOn: 'both'
      buttonColorize: true
      showNoneButton: true

Thanks
