Infinite loop when no input file is given as argument instead of reading standard input

[CratesDeThebes]

Documentation states that the executable defaults to read stdin and with option -i it uses file as input netlist.
Currently, when running the executable without option, an infinite loop starts and can only be interrupted with CTRL-C keys.

This behaviour is due to the code in ucs.cpp, when no argument is found, a first step opens the input file and searches for --path and --module and then closes the input file. This step should wrapped in a if (infile != NULL) {...} block.

Yes, I confirm this bug. To be honestly, I never used the reading of the STDIN with qucsator and didn't test this. I am not sure when it became broken. If you are using qucsator inside some script, you may specify the input file with -i option. I will provide a fix in the next release.
