David Wahl / Mbed 2 deprecated I2C_Scanner

Scans for I2C devices and prints out the addresses to serial. Scans once at startup and again whenever it receives a "s" over the serial port. When using putty, turn "Local Echo" and "Local line editing" options to "Force On". Tested on a Nucleo F446RE but should be portable to most boards with minimal editing.
