Reimplement spawn-if-no-home config option (#2757)

This reimplements the `spawn-if-no-home` config option from the original Essentials plugin. If set to true, running `/home` without having set a home will send the player to spawn (previous behaviour). If set to false, running `/home` will instead show an error message and not teleport the player anywhere.

Closes #1452.
