Relative URLs inside zipped (contained) epub

[panurge-ws]

In some epubs there are relative links to resources and css as ../Styles/Style.css.
In this way, those resources are not loaded because the URL searched is not valid.

A possibile solution is: inside Renderer replace the "../" inside the url parsers:

EPUBJS.Renderer.prototype.replaceHead
EPUBJS.Renderer.prototype.replaceResources

resources.forEach(function(link){
        var src = link.getAttribute("href"),
            src = src.replace("../",""), 
            full = this.book.settings.contentsPath + src;

Updated to use EPUBJS.core.resolveUrl(base, path)
