Autoclean companies

From OpenTTD

Enable or disable autoclean function. If enabled, companies with no player activity for specified game (autoclean_protected and autoclean_unprotected) time will be destroyed.

For example if you set autoclean_protected to 36 and autoclean_unprotected to 0, password protected companies without activity will be unprotected after three years, all unprotected companies will be destroyed the first next month giving only a little opportunity to steal another player's company and scores. If you keep hi-score statistics of players, this setting might come handy to use. Also beware, that one game can't have more companies of the exact same name even if the older ceased to exist.
