* Support default args in funcref calls - Simplify BFunctionRef by using funcref index - Emit default args when visiting function reference * Move default args gen to second-pass visit * Better error message on param count errors * Check for constructor in MTH_NEW * Address self-review comments - Update code comments * Introduce ResourceManager to pol testsuite - Create a new class-based resource manager for deleting resources (item NPCs, multis) after each test. - Migrate house_set_multiid test to use new ResourceManager. * Move resource cleanup
