Switches change state when running `bin/generate_events.py` multiple times after quitting

[Qubitol]

Generate a random process, like

generate g g > t t~
output TEST

Then go to TEST/ and

./bin/generate_events

This will show the following question:

The following switches determine which programs are run:
/=================== Description ===================|================ values =================|======================== other options ========================\
| 1. Choose the shower/hadronization program        |        shower = OFF                     |     Pythia8                                                   |
| 2. Choose the detector simulation program         |      detector = Not Avail.              |     Please install module                                     |
| 3. Choose an analysis package (plot/convert)      |      analysis = Not Avail.              |     Please install module                                     |
| 4. Decay onshell particles                        |       madspin = OFF                     |     ON|onshell|madspin|full|PA|none|madspin_v1|onshell_v1     |
| 5. Add weights to events for new hypp.            |      reweight = OFF                     |     ON|density                                                |
\=============================================================================================================================================================/
 You can also edit the following cards:
/------------------------------------------------------------\
|  6. param : param_card.dat                                 |
|  7. run   : run_card.toml                                  |
\------------------------------------------------------------/
 you can also
   - enter the path to a valid card or banner.
   - use the 'set' command to modify a parameter directly.

If user quits (it does not happen when it gives ok and goes ahead with the generation), and then re-runs:

./bin/generate_events

Now the question shows:

As you can see, all the installed switches changed state (shower, madspin, and reweight in this example).

I noticed this bug as well. Related: in https://github.com/MadGraphTeam/MadGraph7/tree/feat-nicer-interface I was playing around with improving the prompt after launch, especially not printing it out again after every set command

Yes, I agree on that.
Incidentally, I noticed that when we submit a launch with a script containing set commands, there is no logging whether each set command has been executed.
I propose we should have some kind of confirmation that a set command worked or not even when submitting through script.
