This changeset adds the HAL for the ATmega32U4 as described at: https://cdn.sparkfun.com/datasheets/Dev/Arduino/Boards/ProMicro16MHzv1.pdf

After further investigation (see this comment) this changeset is only implementing USART1 and the default Pro Mini serial is USB based. Pending USART1 validation by @kyuzumaki when possible.
