Hi,

Just a quick bug report for Chisel in Minecraft 1.10.2. I've yet to test this in 1.11 - if someone would like to confirm this, that'd be great;

Issue Information

• Minecraft 1.10.2
• Minecraft Forge 12.13.3.2281
• Chisel 0.0.10.22 (Latest on CurseForge at the time)
• Environment FTB Beyond 1.7.0

Issue Description

When using the Chisel to exchange blocks with another variant in world, the Chisel will take durability and in doing so the tool will eventually break. The issue here is that the Chisel's contents (Accessed via the GUI) will not be dropped by the chisel upon breaking therefore leading to the loss of blocks.

Issue Fix

Drop the Chisel's content upon the tool breaking.

Issue Reproduction

1. Open Chisel GUI and place some variant of a block that you wish to replace in world
2. Close the GUI and start exchanging blocks
3. Continue to do this till Chisel breaks
4. Note that the contents is not dropped.
5. Now cry because I lost fancy blocks 😭
