Throw a FATAL when the PWD is set to a different directory than "Origin"

[Lisias]

KSP relies on the current directory in order to access some critical files (as KSP.log)

However, on some borderline situations the OS' launcher may set the working directory to somewhere else, and this is confusing KSP, leading it to bork.

Interesting quotes:

You'll notice that my file manager has an integrated tree-style thing going on. That means I can open folders and then open files from inside those folders without having to actually navigate into them. I use this all the time.

That's what's causing the problem. When I launch the KSP executable nested inside several open folders like that, its working directory is not the directory the actual file is placed in, but the directory that is currently open in the file manager. In the screenshot's case, that is the folder where I keep all my KSP installs.

My diagnosis was:

This is when things went badly:

[LOG 21:37:08.937] [KSPe.IO.Path] Origin is /mnt/LinuxData/KSP/KSP1-11-1-BUGTEST/game/
[LOG 21:37:08.937] [KSPe.IO.Path] PWD    is /mnt/LinuxData/KSP/

And this is when things are fine:

[LOG 21:44:54.928] [KSPe.IO.Path] Origin is /mnt/LinuxData/KSP/KSP1-11-1-BUGTEST/game/
[LOG 21:44:54.928] [KSPe.IO.Path] PWD    is /mnt/LinuxData/KSP/KSP1-11-1-BUGTEST/game/

Well... Microsoft is innocent on this one (By The Krakens, I think this is the first time I say something like that... )

I find it hard to pinpoint KSP as the source of the fault either, as it's expected that the current directory is set to the directory where the executable is by default on launching applications (even Windows does that - damn, two in a day!).

However, there're situations where you want the current directory to be different - so I'm not really sure if this is a bug of the Manjaro's File Manager, or just am unusual feature biting your SAS.

From KSPe point of view, I can "fix" the problem by brute force my way out if the mess setting the PWD to the Origin internally - but that would not solve KSP's problem, as it will still be looking for files on unexpected places.

In a way or another, I need to cook a new FATAL on KSPe to halt the game loading when the PWD is different from the Origin, as this is an unacceptable situation without a possible work around.

TL;DR of the problem:

[LOG 14:38:26.480] [KSPe] Fatal Error PwdIsNotOrigin was shown. pwd = c:\program files (x86)\steam\SteamApps\common\Kerbal Space Program\ ; origin = C:\Program Files (x86)\Steam\steamapps\c
