bring back dedicated console window for non-release builds

[DanAlbert]

https://www.pyinstaller.org/en/stable/spec-files.html#adding-parameters-to-spec-files shows that we can parameterize parts of the spec file. It'd probably be useful to bring the dedicated console window (the scrolling log window that isn't the one inside the liberation app). It went away in the first place because people complained about it being there, but we can keep it around for preview builds and just remove it in the release builds. The people that are more likely to need it are the people that are running the previews anyway.

Maybe just make it a toggle in the settings, default off, instead of removing it for release builds? Those who would actually want to use it would know how to toggle it on.

Edit: thinking about it more, perhaps it's just easier to remember to turn it off for release builds rather than to add the checkbox, and write the code to read/write it to/from settings file. Ultimately, it won't make all that much difference from the user's perspective.

We can't. It's either on or off per build.
