Wirelessly change settings

Remote sender can now wirelessly change the "onTime" of the receiver.
The sender waits for a new onTime value to be sent into the serial port.
It reads in the ASCII characters from serial port and converts the
represented integer into binary.  It then sends a 2 pulses of a
particular length to tell the receiver that the data is coming, then it
sends the 3 byte binary message as a series of long(1) and short (0)
pulses from the LED.
Wirelessly receive 3 byte message

Reads IR pulses from IR sensor. Records the lengths of the marks and
spaces. Every time it gets a message of pulses it compares the first
mark, first space, and 2nd mark lengths to an onKey. If the key is
matched, it turns on the LED. If the key doesn't match it checks if it
matches a changeKey. If the change key matches, it knows that there is 3
byte message that was sent. It converts the last 2 bytes of the message
into an integer and redefines the ledOntime integer.
