Remove StaticResourceServlet

Hi All,

I'd like to remove org.hippoecm.hst.servlet.StaticResourceServlet before HST-2.20.00RC3 release.
The servlet just enables downloading web application resources. It wasn't so meaningful, but it was needed to demonstrate resource request examples before.
Anyway, the reasons to remove the servlet are as follows:

• It is not used in most site applications.
• Also, it doesn't need to exist in HST-2 framework. You can use <hst:resourceURL/> tag instead.

If there's any concerns, please let me know.

By the way, if your project contains StaticResourceServlet definition and its servlet mapping in web.xml, you should remove those manually with new versions.

Kind regards,

Woonsan
