      - Added STM32CubeMxLauncher (uVision launcher for STM32CubeMX configuration utility)
      - Added documentation for creating projects with MDK and STM32Cube
      - Added project examples created with MDK and STM32Cube:
      -- Blinky for ST Microelectronics STM32F746G-Discovery
      -- emWin GUI_VNC for ST Microelectronics STM32F746G-Discovery
      - Enhanced CMSIS drivers compatibility with STM32CubeMX
      Updated CMSIS drivers:
      - EMAC: Corrected lockup after long runtime

      Added CMSIS-Driver for I2C and SAI
      Updated RTE_Device.h (Ver 1.1.0) adding the SAI driver configurations for SAI1 and SAI2
      Extended File_Demo example (NOR flash drive F0 enabled)
      Extended template file "main.c" with provisions for using CMSIS-RTOS RTX
      Corrected CMSIS Driver USART: The driver incorrectly stopped receiving data when calling the USART_Receive function while the receiver is busy
