Help doc for randomizers should specify if range is inclusive

The randomizers should specify that the lower and upper bounds are inclusive. It appears that PHP always does that, but it may not be clear to the average non-PHP user. There could be a note at the beginning saying "All bounds are inclusive" or even just on the first one, like rand(min,max): Returns an integer between min and max, inclusive.
