Add new option to PartSubtype

[linuxgurugamer]

I added a new option: allowSwitchFromInFlight (defaults to true). This is intended to allow a tank to be able to have different types in the editor, but once in flight, to not allow a tank which contains a toxic material (or something incompatible with other tyupes) to be switched in flight

I need this for my life support mod, IFI, have a new tank which can contains two different types of O2 (switchable in flight) and two other toxic materials, which I don't want switchable in flight

My alternative would be to duplicate the parts, I'm trying to minimize the part count.

Okay so just to clarify the idea would be that if this subtype is selected, you can't switch off of it once in the flight scene?

Also any chance you could change the merge into a rebase? I'd like to keep the commit history clean. If not I can probably figure out how.

I've never done that, would be nervous to try on someone else's mod
I'd suggest reading this, might be helpful, I don't have a lot of time right now to test this:

yes

Just to share, this should be available directly in the GitHub web UI as "Rebase and merge" option in the Merge dropdown button.

I wanted to keep the merge commit on master which unfortunately that option doesn't allow. I merged manually but this is done.
