Automatically sign visual style if 'packthem.exe' is in the current directory

A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]
-> I need to patch uxtheme.dll, or sign the msstyle file to apply it.

Describe the solution you'd like
A clear and concise description of what you want to happen.
-> packthem.exe is a program from Microsoft that can compile msstyles for XP, and can sign msstyles for XP/Vista/7. (It does not work for Windows 10 so exclude it)
so, if the user puts packthem.exe to the current directory, and if msstyleEditor detects that program in the current directory, run packthem -s xxx.msstyles(-s means sign the msstyle) after saving the style

I'll see what I can do. Not sure if you are able to sign despite a dummy signature being in place already, but if you are not then you might want to remove the trailing 144 bytes from the style and try again.

packthem.exe signs with a built in signature that Windows recognizes.

[..] dummy signature being in place already

I am saying the style will have two signatures appended if I am not accounting for this second pass. Probably won't hurt, but I like to mention it.

aha, multiple signing didn't make the OS have an error for me.
