Previously, one mhttpd server could sever several experiments at the same time.
This caused however sometimes problems and was hard to maintain. Starting from
SVN revision 4348, I removed the multi-experiment support, which I believe is
now a much cleaner implementation. So if several experiments are defined on a
computer, each one need a separate mhttpd process listening on a different
port. The experiment name can now be supplied on the command line to mhttpd
like for any other midas program. I have tested this so far at two experiments
at PSI, but this does not cover all possibilities. What I did not try was
experiments with web passwords and odb passwords. If there is any problem after
upgrading to 4348, please report.
