Fixed a bug in the Routine system that caused crashes when constructed with only the first three arguments because it wasn't attached. Implemented a gentle release of functions to not release them if the reference count is 1. Adjusted the Routine and Command system to not be necessary to include them in the module core. Moved the INI and XML libraries into their own namespace. Various other modifications and fixes.
