Made the nightly performance test execution
make the resulting graphs and update them.
This means that every night, we should
automatically get a new set of graphs at:

http://insidecray/~bradc/performance/performance.html

For users who run the nightly script by hand
(are there any anymore? :), you can generate
your own set of graphs by setting CHPL_TEST_PERF_DIR
in your environment, placing a Makefile there, and
running nightly -debug -performance.  After the
performance tests have run, it will cd to your
directory and make whatever the Makefile does (the
cron job Makefile builds the graphs and copies them
into my web space).
