Set a specific item of the history
Useage: histGet(num, buflen, string)
num == 0 -> add a "newest" entry to the history
num < 0 -> change the num'th newest entry of the history
num > 0 -> change the num'th oldest entry of the history
positive num's correspond to item ID (not relative to nummin!)
negative ones are added to nummax
