(Question or possible feature request) verifying files in subfolders.

[TomTurbine]

Wanting to verify files, all of them are present and included in the md5 files, but like to keep them separated into subfolders to keep things organized. Is it possible to have RapidCRC-Unicode to scan the folder it starts in and all subfolders recursively in it to verify an MD5 file?

Bonus if it can also show any extra files it finds that aren't listed in the MD5 file.
