a minor suggestion about floorbots

[The Gorog]

I never really used the floorbot. Does it only fix space holes, or will it place down those tiles that you can crowbar?
If it would be the second, you could abuse it to make infinite floortiles and I believe infinite materials from that.

Otherwise I couldnt see a reason as to why it should have a limited supply. Also these and the cleanbots seem way slower then Id personally like them to be.
