Win32 client released

Thanks to MSVC++ Express I was able to write a reliable Win32 client, si_reader.exe with the following features:

- Read data from serial port ( serial main station or USB station with USB-Serial bridge driver for Win32 )
- Alternatively read data from input file created by client
- Save data to file (later to be used by client to send data to FreePunch server)
- Send data to FreePunch server
