#1 Patch for start.bat and stop.bat

[Mike Hostetler]

Attached is a patch for both the start.bat and
stop.bat. It changes both files to do the following:

* sets CATALINA_PATH to %CD%\mudslide, which seems
to work better than letting the Tomcat scripts do it.
* checks to see if JAVA_HOME is already defined,
and uses that instead of setting it.
