Added Native NSMenu support, eventlistener and log-NSLog bridge

It's possible to add menus with:
macgap.menus.addMenu({menuTitle: 'MacGap', menuItems: [{title: 'Menu
Item 1', key: 'cmd+l'}, {title: 'Menu Item 2', key:
'alt+cmd+shift+h'}]});

Display log info in Xcode/Console.app with:
macgap.app.log('Hi!!');

I have removed autload of the google site. It's pointless.
