[SERVER] Add timer task for saving cache maps
Cache maps will now be saved periodically, but only if either they have
a "dirty" bit set, which happens if any bits in the map get cleared
again (due to corruption), or if new data has been replicated from an
uplink server. This either means at least one byte received and 5
minutes have passed, or at least 500MB have been downloaded. The timer
currently runs every 20 seconds.
