clickthrough secretly picks wrong connectivity manager.

When starting a new savegame, kOS opens up a dialog box on the first KSC scene load. So does the Remote Tech mod. Both of these dialogs appear centered on the screen. It's a race condition which box ends up on top.

When the RT box ends up on top, it completely hides the kOS box, so the user doesn't even know it's there. (See screenshot 1 below).

These boxes are not click-through protected. When the user picks options in the RT box, they can be secretly also picking an answer to the question in the kOS box that they never even saw.

Because of this, I ended up starting a remote tech career with kOS's "PermitAll" connectivity manager chosen and I didn't even see it. Instead I kept wondering, "Why on earth didn't it ask me for connectivity manager? Isn't it supposed to?" I did some debugging before finding out that it was actually there, but I was clicking through to pick a button and making the kOS dialog box go away before I saw it.

The second screenshot below shows how that clickthrough happened (with my window shifted aside so you can see it).

Github didn't like it when I tried to put two screenshots on the same comment, so here's the second screenshot, in a second comment:

I tried dealing with this for a bit and found I was hitting a brick wall in that we are using KSP's high level dialog box API (i.e. calling:

                Module.kOSSettingsChecker.QueueDialog(
                    new MultiOptionDialog(
                  //... (etc...)

And this call isn't letting me easily move the box to somewhere else (it has a Rect parameter, but I can't use it to force the box to move - it seems to be getting ignored).

I suspect that fixing this would involve us having to use a home-grown dialog box, not the one KSP comes with.
