simulation: Set current directory to project before run custom simulator

[NhatKhai]

Hi,
  I'm using ngpsice, and use to run it from the netlist generator with specified command, and the "Run" button. However, I found that the ngspice tool do not understand windows system absolute file path that automatically send by KiCad. So I found my work around is that start KiCad from the current project folder, so that the eeschema will start the ngpsice from current project path, and I can pass it just only the netlist filename (relative path) to have it work everytime.

  So it would be nice, if the "Run" button from netlist generation automatically adjust current folder to project and pass relative path of generated netlist file to ngspice/any sim. before run would be nice.

What is the spice commandline you use?

Running spice from the export netlist dialog is no longer supported.
