Description

The Multibuilder, in SWAP mode, could swap the material of Slimefun blocks. This allows the duping of blocks on a 1 by 1 basis. In the example provided on the Slimefun Discord, the Powered Bedrock block from Infinity Expansion constantly set's it's material back which allowed for a very fast and powerful dupe.

Changes

Given the potential issues, and that all STB blocks are also exempt from swapping, I have added a Blockstorage check to the canReplace() method should Simefun be present.
Added a isSlimefunEnabled variable and a getter to SensibleToolboxPlugin.java
