First is the inclusion of two new projects: SabreHelper and SingleGame. SabreHelper is a DLL that contains anything that might be in common between programs (converters, db tools, logging). SingleGame is an experimental program to minimize a DAT for server usage, requested by Kludge.
The new structure represents a cleaner approach to having helper functions in a DLL, making each individual executable smaller and more well-defined.
Headerer now does both deheadering and reheadering. When a file has a header detected, it puts an entry in the database with the header, unheadered sha1, and the rom type. Reheadering tries to find a matching sha1 in the database and then adds it if it's found.
