Island name (#8)

* Add island name checking and renaming functionality

Added a method in the IslandData class to check for duplicate island names and a new class IslandName to handle island name-related commands. These changes allow players to rename their islands while enforcing uniqueness and certain length restrictions on the names.

* Update island name in island data cache when renamed

Modified the 'islandName' method in the 'Island' class to make sure that any changes made to an island's name are also updated in the island data cache. This ensures that all references to the island's name are consistent and accurate throughout the application.
