(svn r12913) -Add: ability to backup and restore a player's economic data and data for a vehicle (or chain of vehicles)

Browse Source 
Autoreplace uses this with the following benefits:
  -Mass autoreplace (the button in the depot window) will now estimate costs correctly
  -Autoreplace now either replaces correctly or manages to keep the original vehicle (no more broken trains)
  Thanks to Ammler for testing this
