Version
1.4

Makes a standard stream for the HvA-Xmegaboard. It is build on the wrapper. With these you can use printf and scanf to write to and read from the UART F0. The baud rate is 115200 and the protocol is 8N1.

Version 1.3 : Modified uart_fputc changed. With a full TX-buffer it doesn't skips characters anymore. It now waits until there is free space in the buffer.

Version 1.4 : The baud rate is changed toe 115200
