Adds progress bars to Kittens Game to see how close you are to an upgrade
This script is for Kittens Game and simply adds in Progress Bars that show how close you are to being able to build something, akin to the Android version of the game. The Progress Bars should automatically color themselves according to the theme you have selected (it uses the color of the theme's disabled button text), but for simplicity's sake requires a page reload if you change themes.
Original code is modified from lyuhau to work with current versions of Kittens Game
