This replaces the experimental validators module with foundational code to implement a new system for tracking validators, validations and the UNL. The code is turned off by default, in BeastConfig.h * Remove obsolete public Manager interfaces * Remove obsolete database methods * Remove obsolete ChosenList concept * Remove obsolete code * Add missing includes * Tidy up STValidation.h * Move factory function to Validators::make_Manager * Add Connection object for tracking STValidations
