Statizier: Allow dinamic sites to be indexed by searchers

A simple way to hide dinamic sites to web spiders so they can index it.

Almost all web-spiders (like Google) can not index dinamic sites due to the parameters present on almost all links in the site.

This class, along with a simple modification onto your Apache configuration file, allows you to hide all the parameters and dinamic links and URLs of your site, so all web spiders will crawl it.

The best of all is that this will not give you too much work to get it working in your dinamic site.
