Patcher object reference

Every patcher object that patcher::CreateObject knows about — 305 in all — grouped by category, one page per category. The category is the same one a host editor reads through the C API metadata (yse_patcher_get_type_category and the "category" key of yse_patcher_get_metadata_json) to build its object palette.
