ENH: add possibility to enable/disable profiling globally (issue #441)

- use InfoSwitch to disable, or via static method.

- respect the state of the argList banner when deciding to emit
  initialization information. Can otherwise end up with unwanted
  output rubbish on things like foamDictionary and foamListTimes.
