Fix bad button position in setup dialog, make the SetupDialog fixed size and EffectDialog resizeable

[Umcaruje]

Fixes #1849

Before & After:

[zonkmachine]

Tested - fixed. There is another thing in there that's a bit odd. If you grab the right edge of the window and expand it to the right it will follow and the OK/Cancel buttons too, but not the text entry fields. The way I see it either they follow or the frame should be fixed.

Duplicate of #1849.

Ok, so, I decided to make the setup dialog fixed size, so we avoid the resize problems. I also did the same thing for EffectDialog. Comments welcome.

Looks good although I'm not a fan of all of the code editor auto-formatting changes as they makes the PR harder to read and can really make the cherry-pick process harder down the road.

I'd rather we fix formatting in separate PRs, personally.

Yeah, I agree, I'll see to disable it in atom and redo this PR.

@tresf done. Anything else that I need to change?

[Umcaruje]

Ok, so I thought about it, and it really doesn't make sense to have the RenameDialog fixed size. So I made it resizeable:

As always, testing and comments welcome.

Side note on this... I feel we shouldn't get too comfortable with the resize hacks, but rather use containers which can handle resizing properly. That said, looks *good.
