Spice4qucs tests

[ra3xdh]

I have just added tests for qucs+ngspice backend. Both netlist and simulation tests were implemented. Sources are here: https://github.com/ra3xdh/qucs-test/tree/spice4qucs There was added four test projects:

• NG_RCL_prj RCL circuit --- AC+TRAN
• NG_BJT_prj BJT amplifier --- AC+TRAN
• NG_BJT-swp_prj BJT amplifier --- AC+TRAN+Parameter sweep
• NG_EDD-Q-test_prj Charge equations with EDD (Nonlinear capacitor) --- AC+TRAN

How it works: run.py automatically recognizes project names starting with NG_ and executes ngspice+qucs instead of qucsator.

I also have introduced command line option "--ngspice" for run.py. It have effect only together with --add-test or --reset. If this option is passsed schematic will be treated as ngspice simulation.

How to add new simulation tets:

run.py --add-test Schematic.sch --prefix where_qucs_installed/ --ngspice

I left --qucsator switch for ngspice-tests too. Test could be run as usual:

$ ./run.py --qucsator --project NG_EDD-Q-test_prj --prefix /mnt/Data2/qucs-0.0.19/bin/ 
Using Max. time: 90
Using rtol: 0.1
Using atol: 1e-05
Found Qucsator in: ['/mnt/Datei_2/qucs-0.0.19/bin/']

You need to use latest build of Qucs from rebase_spice4qucs branch with this modified testsuite.

I am bit confused to call --qucsator and run ngspice in the background.
I will try to run it locally.

I think we can in future replace --qucsator by --simulator (If multi-simulator paradigm will be accepted). It will mean "run all available simulations". Now I decided to preserve legacy options to avoid breaking anything.
