Re #48 - Require schemas to validate
 * Restructure schema caching so that it warns instead of exceptioning - allows a missing schema to not kill an unrelated file load
 * Fix exception handling for GameSystems while working out where exceptions were being caught
Current situation: Missing Race/System schema stops file loading but missing cat/core schema doesn't
