Multiple changes

Working on async schematic saving
Default plot clearing is now properly async (and somewhat slower)
Offline mode servers now default to lowercase (there has been ample time
to update)
Fixed some issues with plot expiry
Fixed some issues with UUID caching
Optimized UUID fetching from cache (marginal)
