New feature. Brim tail.

[Shdlk]

Hi

Let's add few cm tails to the brim and to Support_brim. It would significantly help to remove prints (brims) from the plate.

I suggest making a few extra layers at the end of the brim (in case of support_brim - one tail per one support_brim). This will make it easy to pick up the plastic (brim) and remove it from the plate.
