Changes: Added parameters for optional scrollbars, resizablility,
menubar, toolbar, addressbar, statusbar, fullscreen. Also tweaked the
implementation a bit - links will now give the user a popup window
even if JavaScript is disabled.

Notes: Some parameters are not cross-browser capable (e.g. fullscreen).
Browsers that do not support these abilities will ignore them.

Usage: The link is written as follows: 
onclick="newWindow(this.href, 'popup', 600, 500, 1, 1, 0, 0, 0, 1, 0);

Usage Description:
"this.href" refers to the URL given in the "a" tag; "'popup'" is the name of the popup window;
600 is the width of the popup window; 500 is the height of the popup window; the numbers that
follow designate whether a property is turned on ("1") or off ("0"), in this order:
scrollbars, resizable, menubar, toolbar, addressbar, statusbar, fullscreen

function popup(url, nombre, ancho, alto, propiedades) {
   var izq = (screen.width - ancho) / 2;
   var arr = (screen.height - alto) / 2;
   window.open(url, nombre, 'width=' + ancho + ',height=' + alto + ',left=' + izq + ',top=' + arr + ',' + propiedades);
