new feature: JSpecView PEAK command -- adds PEAK GC/MS "#1"
-- #1 here indicates "MS for first GC peak"
bug fix: JSpecView GC/MS issues
bug fix: JSmol callbacks should refer to "jmolApplet0" not "jmolApplet0_object"
bug fix: set cameraDepth not working
-- note that loading of PyMOL files affects this setting, which
is reset only using the INITIALIZE command
