changed 1 line so split files dont come in a sub directory

[stefan-STMODE]

Hello Clouz, I love this simpel tool. i changed 1 line, maybe u can make it optional also?

I needed the splitted files in the same directory

So i changed line 225 in PDFInterface.cs
//string outFiles = OutDir + Path.AltDirectorySeparatorChar + Path.GetFileNameWithoutExtension(InFiles);
string outFiles = OutDir;
