Dirty highlight option to find the icons easier

whilst looking for a certain icon i have to resort to the browsers search and clicking next next next.. so i just threw this together from a previous project i did for jquery ui icons. it can definitely be improved on. not sure if you keen or not

at the moment when you start typing it fades the other icons and highlights matches based on `$(".the-icons i[class*='" + term + "']")`
