Hugo's Lonely Planet UI test

I've commented the changes in the source files but here are the highlights:

- Added a few meta and favicons entries in the header. Either to comply with HTML5 or to add better support for facebook, iOS devices and other mobile.
- Changed some HTML markup to improve semantics.
- Changed the 3 images to the proper layout size, this way saved almost 45% of bandwidth. 
- In the spirit of Responsive Design I've converted the CSS to better handle different resolutions.
- Minifyed CSS.
- Changed the javascript to fetch the original image size on click
- Added the possibility of closing the lightbox by clicking on it.
