Major changes to structure and code

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.
