Windows : Improve opening of USB serial emulation and all other port

[GoogleCodeExporter]

I was not able to open any serial port created by a FTDI USB/serial device.

A simple workaround could allow this. In "win_qextserialport.cpp", function
"open" :
Win_Handle=CreateFileA(port.toAscii(), GENERIC_READ|GENERIC_WRITE,
                              FILE_SHARE_READ|FILE_SHARE_WRITE, NULL,
OPEN_EXISTING, 0, NULL);

Require to add a path to port name : 

Win_Handle=CreateFileA("\\\\.\\"+port.toAscii(), GENERIC_READ|GENERIC_WRITE,
                              FILE_SHARE_READ|FILE_SHARE_WRITE, NULL,
OPEN_EXISTING, 0, NULL);

All COM port numbers greater 9 are effected. In order to use them one should 
use this modified call. I included this change in the attached patch. (I hope 
it works, the last patch creation was some time ago.)
