Added support for monospacing alignment modes to HUDFont / BaseStatusBar.DrawString

[Player701]

This PR adds support for monospacing alignment modes to HUDFont (and therefore to BaseStatusBar.DrawString). See here for details. Updated test WAD / screenshot can be found in the thread.

I would rather give the underlying type like int to EMonospacing enumeration, and replace #include "v_video.h" with just a declaration.

[Player701]

Sorry, I'm not particularly familiar with these C++ quirks, so I'm not quite sure what kind of declaration you're talking about... I think you are allowed to push changes to my PR branch, so I'd be happy if you could fix it for me.

The problem is that the size of EMonospacing is not well defined. Such types shouldn't be used in a script export because they can cause undefined behavior.. So either make the member variable an int or make the enum an int by declaring it as enum EMonospacing : int

[Player701]

OK, I've added an underlying type declaration to EMonospacing, but I'm still not sure what I should replace #include "v_video.h" with.

[alexey-lysiuk]

With enum EMonospacing : int;

[Player701]

OK, done.

Now I would say "squash everything to one commit", but it's better to wait for Graf's final word on this topic.

Thanks. Now I can finally get rid of that lousy hack in my mod code...
