st.onCache — Cache Change Listeners

-- Listen for changes to a cache key
st.onCache('ped', function(newValue, oldValue)
    print('Ped changed from', oldValue, 'to', newValue)
end)

st.onCache('serverId', function(id)
    print('New server ID:', id)
end)

Cache change events are fired via 'st_libs:cache:<key>' net events internally.
