Impossible to set vpadding/hpadding using grunt

[stalniy]

Currently it's impossible to specify vpadding/hpadding options for sprite image. As I see from source code this.options for SpriteSheetConfiguration class is not set but then inside method layoutImages you passes this options into Layout constructor:

//builder.coffee L: 187
      layout = new Layout()
      @layout = layout.layout @images, @options

+1. This padding is very useful getting sprite images not to overflow into one another when the browser is zoomed.
