Doing it in BuildCraft 6.1.4 (apologies to implementers!) as there are a few things which MUST be done in order to make builders behave in a sane way (no dupebugs, etc.)

• SchematicRegistry is now ISchematicRegistry and accesed via BuilderAPI.schematicRegistry.
• BREAK_ENERGY and BUILD_ENERGY are also stored in the BuilderAPI class.
• Most of the functions in Schematic have been renamed - see 24b4859
