XSLWeb release v4.0.0-RC-3

Since v4.0.0-RC2:

• Several bugs fixes.
• The XSLWeb build profiles for Saxon PE and Saxon EE now download the Saxon jars from Saxonica's Maven repository; no more need to install them in your local Maven repository (see [Support for Saxon PE (Professional) and EE (Enterprise Edition)].(https://armatiek.github.io/xslweb/XSLWeb%20Developer%20Manual.html#support-for-saxon-pe-professional-and-ee-enterprise-edition))
• Serving of static files (StaticResourceFilter, ResourceSerializer) is now handled by a new FileServlet (based on org.omnifaces.servlet.FileServlet) with more extensive support for ETag, If-None-Match and If-Modified-Since caching requests and Range and If-Range ranging requests ("byte serving").
• Added documentation about events and cross site scripting prevention.
• The request XML document is now also passed as stylesheet parameter $req:request-xml-doc to all pipeline transformation steps (see Stylesheet Parameters)
• Added a new XPath extension function transform().
• FIX: The EXPath extension function "file:resolve-path()" now returns absolute paths "as-is" (breaking change).
• Added new logging XPath extension functions debug(), warn(), error(), info(), trace().
• Initial release of the "XSLWeb Debugger" (experimental!).
