[EMU] RomCenter 4.0.1

Here is the first fix for 4.0. Not a lot of bugs, and most are fixed in this version
Requirement : .net framework 4, windows xp to windows 10
The 4.0 branch will be the last version compatible with windows XP (<3% of romcenter users are on xp).
4.1 branch will use a modern framework (4.6 or 4.7) which will allow powerfull language features. Also, I'm testing a 64 bit version, which hopefully will solve memory problems.

- Add support for samples with extension in datafile
- Add new arcade datafiles: itech32, namco s12, nmk16, seta 1, sony zn1/2
