Extended error strings on UNIX

[GoogleCodeExporter]

I have tried to open a port without the sufficent R/W privileges and the lib 
said me that the file does not exists. Well it was a bit misleading, so I have 
modified a bit the UNIX serial port opening code to use the errno variable to 
make it more verbose. 

Also I have added a comment to the QextPortInfo physName member, and pushed the 
Ctrl+I in some files (auto identation in QtCreator)
