Patching extra functionality into <gamemd.exe>

[pd]

It's not that much work but actually, I also think it's better not to let it be determined by a tag. Besides, you'd have to set that flag for the old countries, too, and that would be against my compability rule.

I finished my work on the countries, you can have 89 new ones in total .
Why 89? Well, the last country would be 99, it loads the flag c99_flag.pcx.
c100_flag.pcx wouldn't work because 100 has 3 digits. I could change that, but isn't 89 enough...?
Besides, I didn't test having 89 countries. But I tested 20, and it works.
As I said, I also fixed the sidec03.mix stuff, a new patch version should be released tomorrow I think.

@ Marshall:
I dunno what's wrong, but the infantry deaths work wonderful for me. Maybe you made the "end of file mistake" like DCoder? Or used [NewInfantryDeaths] instead of [NewInfDeaths] (I make that mistake sometimes )?
I hope you can fix it.
