Humidity component

Humidity and temperature sensor using an SHT21 IC connected via I2C - as used by the Matrix e-block module EBM016. On screen GUI allows temperature and humidity values to be simulated, and will show all I2C communication in a console window.

	Stop Delay
On older microcontroller devices there is a potential for the I2C hardware channel to lock up if there is not a 10ms delay between an I2C stop event and the next I2C start event. Most modern microcontrollers will not have a problem so this property can be disabled to speed up the I2C communications.
