scripts/framework/HTTP.js ignores port parameter and protocoll

[Johannes Gerer]

1. the protocoll is complete ignored, so you change you example (which uses http://host into just "host")
   As only http:// seems to be possible on APE that would be enough for now.
2. If no port is given in the url via url:port, then the port is always set to 80 even if one is given in the constructor!

My fix is to have he following priority: Constructor Agrument or, if none given: port in url, or if none given: 80

initialize: function(url, port) {
    this.url            = url;
    this.port           = port;
    this.parseURL();
},

parseURL: function() {
    var result  = this.url.match("^.*?://(.*?)(:([0-9]+))?((/.*)|)$");
    this.host   = result[1];
    this.port   = this.port || result[3] || 80;
    this.query  = result[4];
},
