learned that java.policy.applet is crap that Eclipse does and updated .gitignore accordingly
Figured out how to use packages and fixed index.html and refresh and deleted prepare.py as it was no longer needed.  Turns out that I wasn't putting the class files into folders when I moved them over to the server, so they were no longer in the packages in which they thought they would be.  Then when I thought that I could bypass that by calling them from the package in the html file, it wasn't able to find those folders, so it made further errors.  Solution: put the class files into their package folders and then adjust index.html so it calls on Applet.java from the appropriate folder.  I still need to fix the servlet calls.
