Command line and user config file

I have made two small changes to IsaViz that I wanted to share.  First,
I noticed that IsaViz allows command-line arguments, but they are not
passed through to the class invocation in the /bin/sh wrapper (run.sh) -
changing the last line to the following solves the problem:

    $ISAVIZ_HOME/lib/antlr.debug.jar" org.w3c.IsaViz.Editor "$@"

I have not provided a diff because I have otherwise modified the file;
my apologies.

The other change that I made was to store individual IsaViz
configuration in a "dot" file in the user's home directory, which
follows standard Unix (and kin) conventions.  The attached patch should
do it.

This is all against version 2.0, so I may be out of date, in which case
I apologize (again).

Take care,
