1. Coop play. /is coop <player> adds a player you your island
temporarily until they log out or you expel them.
2. Improved island delete - this change requires there to be a minimum
16 block difference between Island Distance and Island Protection
ranges. As a result, the default Island Protection range changes to 94
from 100. If you try to make it less, it will be set to be 16 different.
For upgraders, this means that islands will be slightly smaller.
3. Improved island guard - [INCOMPLETE] - checks based on where the
action is happening rather than the position of the player. Makes the
outside limit of the island better defined.
4. Added locale strings for these features.
