Replace restore() method with second optional parameter when instantiating Characteristic 

To enable save/restore for a Characteristic, set second parameter to TRUE when instantiating.  Since first parameter was optional as well, this requires setting it as well.

Next up:  Must add logic to setVal() to store new value as well.
