Fix tomcat startup in nb installer

The installer fails to load in my virtual machine. My jakarta_service___.log file has entries like this:

[17:05:48|2009-02-18] [ javajni.c|174] [error] The specified module could not be found.
[17:05:48|2009-02-18] [ prunsrv.c|994] [error] Failed creating java C:\Program Files\Java\jre6\bin\server\jvm.dll
[17:05:48|2009-02-18] [prunsrv.c|1269] [error] ServiceStart returned 1

Copying "C:\Program Files\Java\jre6\bin\msvcr71.dll" to C:\Windows\System made this work.

We need to either switch to Java5 in the installer until this discrepancy is resolved between tomcat6/java6, or add that dll to the path somehow (either by copying or by putting it in the environment variable)
