[SECURITY] Fedora 15 Update: clearsilver-0.10.5-15.fc15

ClearSilver is a fast, powerful, and language-neutral HTML template system. In both static content sites and dynamic HTML applications, it provides a separation between presentation code and application logic which makes working with your project easier. The design of ClearSilver began in 1999, and evolved during its use at onelist.com, egroups.com, and Yahoo! Groups. Today many other projects and websites are using it.
