Fabio Fumi / Mbed 2 deprecated Speaker_test

Basic speaker testing on a STM32L053R8 board. Based on other examples and improved using commands sent from PC over serial-USB (t=Tone, s=Sweep, p=Police, h=Song, space=Exit). A small 8-Ohm speaker directly plugged on GND/PA_0 (PWM out) makes a low but clearly audible sound.
