Tutorials: “Customize styles in Sandvox” updated

One of the most viewed pages in this website is the tutorial to customize styles in Sandvox via CSS injection. The tutorial was written for Sandvox 1 and a few things are changed in Sandvox 2.

The best one is the possibility to inject code directly into the CSS file, saving a few bytes and making things cleaner and easier.

I wrote again the tutorial from scratch and I think it is now even easier to follow, with more examples and few more informations about how code works behind the scenes.
