Tons of slight changes

Hi,

I made some changes, here a small resume:

- Improved CSS, less code = faster loading.
- Started adaptation to HTML5 for passing the W3C validation (http://validator.w3.org/)
- Slight improvemnt in generation scripts

TODO:

- Less JavaScript, some scripts are unnecessary and could be replaced with some simple HTML5 features.
- Improve news _post_ presentation
- Improve the loading of the photo gallery _ImageMagick? script_    

That's it all friend.
