-- returns a vnum from a table.
-- the table must look like this:
-- items = {
-- 	{vnum, probability[, minLevel[, maxLevel] ]}[, ...]
-- }
-- vnum is the vnum to be returned
-- probability is an int showing how often this vnum should be returned compared to the others
-- minLevel is the minimum level a player should have in order to return this vnum
-- maxLevel is the maximum level a player should have in order to return this vnum
-- -- WARNING: don't use levelLimit in server_timer triggers, the server will crash!
-- 
-- e.g:
-- items = {
-- 	{101, 1},
-- 	{102, 2, 20, 50}
-- }
-- will return vnum 101 with a probability of 1/3. When player is below level 20 the probability will be 1/1.
-- returns 102 with a probability of 2/3 when the player is between level 20 and 50, otherwise not.
