[Suggestion] Purge archaic claims and reset chunks to initial state

[Lumijiez]

GT:NH is a very old and unwipe-able server, especially the Overworld, and throughout the years it's been filled with bases of player that have spent less than two hours playing the pack and went inactive for years. Their bases now occupy good and attractive space for other players to setup their bases. I suggest going through the Townlist and purging bases that have players inactive for longer than 1-2 years. 

The number of years chosen is based on the average time it takes for a wipe to occur on other servers, plus perhaps one year. By removing those towns and resetting the chunks to the initial state, we will manage to keep the world fresh and clean for new players, without trash-scattered parts of the world full of bases that haven't even begun the Steam Age and whose owners last joined 3 years ago.
