ROOTLING: weak hostile mob for low danger caves

A mob which appears to be made of clumped together roots and dirt. (unclear as to why it is even alive) it does very little damage but upon hitting the player it "roots" them: stops them from moving almost entirely and temporarily reduces mouse sensativity, to escape the player must just move around a bit to free themselves. When killed the rootling drops 0-1 roots and rarely 1% or so rooted dirt.
