[REQ] Support for relative paths "dot-slash" in checksum files

[DanielSmedegaardBuus]

Hello :)

Thanks for making an open-source checksum tool for Windows!

I have files (MD5 in this case) that contain relatives paths starting with .\, e.g. .\Subdir\file.ext, and ilSFV says they're all "missing." It'd be nice if it would handle paths like these correctly :)

Thanks again
