New thralls: Builders

Hello there! I have interesting Idea for the new thrall type - builders. And builder’s workbench as workplace for them. At builder’s bench you can create a pattern. When you activate this pattern in your inventory, you open design menu where you can freely build with transparent blocks. Transparent blocks represent building blocks (just like in building menu). When you finish, you close design menu, place at builder’s bench a builder thrall, edited pattern and nessessary building blocks. And thrall start building according your pattern and building blocks that you placed at bench. I know it’s could be tricky to made, don’t judge strictly
