Simplify smoke test: SpringBoard-Core is already a valid Spring archive

You're right - no need to manually copy directories!
SpringBoard-Core is already structured as a complete .sdd archive.

Just symlink the entire checkout as 'SpringBoard Core.sdd' and it works.
This includes all necessary directories automatically:
- LuaUI, LuaRules, LuaHandler
- scen_edit, triggers, libs_sb
- modinfo.lua
- Everything else

Much simpler and less error-prone!
