  Log:
  Stage 3 of making Jasper work without an XML parser in the "lib"
  directory.  As you can see, it was a little more involved than originally
  planned.  Notes on what is going on:
  
  * A new directory, $CATALINA_HOME/jasper, contains the portions of Jasper
    that compile new JSP pages -- plus the XML parser that they need.
  
  * The jaxp.jar and crimson.jar files have been moved from "lib" to
    "jasper", so that they will not show up in the class loader hierarchy
    as seen by a web app.  Thus, an application that wants to run Xerces
    (by putting xerces.jar in WEB-INF/lib) should no longer have a problem.
  
  * The runtime portions of Jasper (i.e. the code needed by an already
    compiled JSP page) remains in the "lib" directory.  As you can see from
    the modified build.xml file, the current code organization is really
    awful - anyone interested in working on a complete overhaul?
  
  * Catalina was modified such that, *if and only if* a web application uses
    JSPs, a class loader that is a child of the web app class loader is
    created, picking up the contents of the "jasper" directory.
  
  * All Watchdog 4.0 tests currently pass.  I'm running other tests to
    make sure I didn't break anything accidentally, and would appreciate
    it if others did the same.
