Update qucs_run_hdl.bat to use GHDL on Windows

*** UNTESTED! ***

This should complete #395 but I am not able to build and test Qucs-S on Windows at the moment. Please can someone test this before proceeding any further.

The BAT doesn't work for me. The error message is shown on the screenshot. I suspect the problem with %TIME% variable. Maybe my GHDL windows package is wrong, because the same circuit works using Linux package. You may use this demo package to test the GHDL on Windows https://drive.google.com/file/d/1-anZcfQK9heIn0d9nmqSGqHlPXDfOjUh/view?usp=sharing Everything should work using 64-bit wine.

The simulation operates after setting time=12n without unit in the simulation properties. But GHDL shows an another error coming from the VHDL file itself. It's strange that the same file works on Linux without problem. Maybe GHDL version for Windows requires an extra configuration.

Please can I check if the Windows build you sent has the fix to qucs/dialogs/simmessage.cpp in faaaff0? There should not be a space between '40' and 'ns'.

I have a workaround, but it would be better to test it against the final code.

But there are also some problems with the batch file. It seems that %DIR% and %TIME% are reserved - at least on my Wine installation. If I change them to %SIMDIR% and %SIMTIME% it seems to work.

Everything works as expected now. Merging.
