reskate.files kept each plugin's folder in Mods/.reskate/data/<plugin>/, inside the merge's own
output, which every full merge deletes: saved Deathrace routes went whenever a mod changed. It is
Mods/.reskate_plugin_data/<plugin>/ now (mod_list.h plugin_data_folder), and what is still in the
old folder moves across the first time the plugin looks for its folder. Deathrace's routes keep
SmokeyDawg58's <map>/<name>.json layout, so routes from his fork copy straight into routes/.
