fixes the installation part.

But as the attached TESTResource.java demonstrates, java itself has a 
problem delivering Class.getResourceAsStream() from inside a .jar file, 
if this .jar file is below a directory containing an exclamation mark.

Since we are making heavy usage of getResourceAsStream(), this means:
 - installer autotests cannot run
 - jython does not startup if installed into a directory containing a 
'!'

To reproduce the java problem mentioned above:
 - compile TESTResource.java
 - put the class file into test.jar, in package st.extreme.jython
 - add a text file my.resource into the same directory st/extreme/jython 
inside test.jar
 - copy test.jar into a directory containing a '!'
 - run the following java command:
java -classpath test.jar st.extreme.jython.TESTResource
 - and it will complain about a null resource stream
