added first-order TPTP version of Nitpick to Isabelle, so that its sources stay in sync with Isabelle and it is easier to install new versions for SystemOnTPTP and CASC -- the tool is called "isabelle nitrox" but is deliberately omitted from the tool list unless the component is explicitly enabled, to avoid clutter
