Random items mutator refuses to spawn classic powerups
g_random_items 1 selects a random powerup between item_jetpack and item_fuel_regen and ignores classic powerups.
This bug was introduced by 7c149ecc where spawnflags = ITEM_FLAG_NORMAL;
is no longer set on item definition but on spawn. If a map lacks a certain powerup, that powerup can't be spawned as replacement by g_random_items because spawnflags is not set.
