BasicTempSensor in it's own header file
Removed check for NULL pointer address in tempSensor - not possible with dynaconfig.

Sensor calibration adjustement.

reworked sensor connect/disconnect functionality.
I used to get repeated messages about the sensors being disconnected. This is fixed. Also a disconnected sensor doesn't hang the system now, since DallasTemperature::isConnected is used as an early test to see if a sensor with the address is present.
output calibration setting with device info
removed mode change in eepromManager::initializeSettings.
The user should always set the mode manually.
TempControl::loadDefaultSettings - call setMode first so default beer temp is set.
fixed constant expression for secs in a day (used to use 60.0, but now 60L.)
Changed simulator command from x to y
