[DatFiles/] Create separate classes for each type of DAT

This DOES group some kinds of DAT due to their inherently similar nature. TSV and CSV are under the same "SeparatedValue" umbrella, and all of the SFV, MD5, SHA1, etc are under Hashfile because they're nearly identical. This is just the first stage change, making everything static and making them reference the DatFile separately.
