Dave and I fixed up the method by which the sitemap is opened today, fixing the problems we've been having with openning guardmedm guardian controls screens.  sitemap is now a script that should be in the path of all users (currently stored at /ligo/apps/linux-x86_64/utils/bin/sitemap).  It works from the command line, and menu bar launchers.  All other references to any other method of openning sitemap should be purged.

All sitemap calls should now also reuse ("-attach" to) the same MEDM session.  If a sitemap is already running, it should raise the already running session.
