Several times some users have expressed the non-intuitive aspect of some of our stat/info metrics and suggested to add some help. This patch replaces the char* arrays with an array of name_desc so that we now have some reserved room to store a description with each stat or info field. These descriptions are currently empty and not reported yet.
