[13.04.2015] Added in trees for moretrees, working out getting proper naming for capitating to work. [14.03.2015] Added sound of a falling tree (taken from there http://www.freesound.org/people/ecfike/sounds/139952/). Made "drop_items" and "drop_leaf" both "true" by default. (mintpick) TODO: — add more trees — add more types of trees — play sound if much nodes are removed — use vector_extras' functions to increase speed — update loop(s)
