- drplot: Removed the call to get(getOption("device")), since it caused

  problems when calling drplot from Sweave code chunks as well as in JGR.
- drplot: Removed the output with cat, since it may be annoying to receive
  a message when a plot was requested
- Small documentation adaptations and fixes
