Colony Patches - Compatibility Fixes for MineColonies

New option: several colonies per player (off by default).

MineColonies lets a player own one colony: a second Town Hall only offers to delete or abandon the first, and its own allowinfinitecolonies setting does not change that. With severalColoniesPerPlayer = true in config/colony_patches-server.toml, a new Town Hall founds another colony, owned by the same player, next to the ones they have. Every colony keeps its own citizens, buildings and permissions. Where MineColonies asks for the colony of a player (/minecolonies home, commands without a colony id, a flag placed outside any colony) it takes one of them.

Tested on a headless server: one player confirmed the founding of three Town Halls 400 blocks apart. With the setting off only the first became a colony; with it on, all three did.

The Compatibility addon for MineColonies 3.58 no longer has its own handling of Cultural Delights corn, so the corn fix has nothing left to do there. The log line about its missing target class is harmless.
