Herpaderp @Abrar :P
No more stupid IndexOutOfBounds error for /feperm.
Test for unknown host error.
Fix for /p user <user> group (added usage).
No file locking until H2 fixes their SOCKET method.
Reverted to /spawnpoint override and made /spawn use the vanilla dimension spawn manager.
Variable length censoring

Added variable length censoring so the number of replaced characters
matches the length of the censored words.
