Revert "Processing Error: "Cannot convert from RadioButton to Toggle" - SOLVED"

This reverts commit 49c170071e227b518b9ce29eabac675d6c9b72ac.

- The problem solved was only a problem if attempting to use
  controlP5_v1.5.2 with Processing 1.5.1.

  While the fix *did* enable use of controlP5_v1.5.2, it also
  (at the very least) prevented any values being displayed under
  the PREFS tab.

  THERFORE - ONLY USE controlP5_0.5.4 with Processing 1.5.1
