Opening the vault is now controlled by the 'randomvault.use' permission, true by default.

(Thanks abhisantos :3)

- Added way to change number of items dropped with new 'itemsamount' argument.

- The size argument now changes how many rows of slots the vault has.

- You can customize what happens when your vault overflows with the new 'toggleoverflow' argument.

- You can customize what notifications get sent with the 'toggleoverflownotif' and 'togglefullnotif' arguments.

Added size setting to determine the number of items to be delivered each batch.

This is nothing special.

- You can now do '/randvault timings' to check the current timings.

- Bugfixes
