allow org.jboss.web.rewrite.RewriteValve rewrite resource to be configurable

add resourcePath attribute setter to valve, so following works:
<Valve className="org.jboss.web.rewrite.RewriteValve" resourcePath="resource:my-rewrite.properties"/>

would like to add valve in deploy/jbossweb.sar/context.xml so its added to all webapps

I can't put it into engine or host element in server.xml, because its added to valve pipeline before error handling valves etc. so rewrite rule with [R=404] would show empty page, not proper error page

I don't want to add a copy of same rewrite.properties to every .war WEB-INF

using rewrite filter to deny access to dot-prefixed files (like .svn, .project, ...) that tomcat would otherwise service as usual
(if there is a better solution than using rewrite filter, I'd like to hear it, but does not change suggested improvement for rewrite filter)
