Changes to generic STM32 board definitions for Serial. The first UATT is now Serial, second is Serial1 (this maps Serial -> UART1, Serial1->UART2 etc). Also fixed missing sprintf, - needed more includes in wirish.h. Also investigated implementing printf for Serial.printf (currently a work in progress)
