random: Remove section from DESIGN

The documentation in the code looks fine, so it doesn't need to be
changed.

-Random:
-	The random number generator is used by the Queue to pick a song as
-	randomly as possible.  I use two different RNG implementations,
-	depending on if Ocarina is compiled with CONFIG_TEST or not.
-
-	When CONFIG_TEST is enabled, the RNG is a simple counter.  Every time
-	_pick_random() is called, the counter is incremented and returned.
-	When compiled without CONFIG_TEST we will return values using the
-	rand() function from stdlib.h.
-
-- API:
-	void random_seed(unsigned int n);
-		Seed the random number generator based on n.
-
-	void random(unsigned int min, unsigned int max);
-		Return a random number between min and max, inclusive.
-		If min >= max: return min.

 Queue:
 	Queues are lists of songs that the user has requested to play.  They
 	are the main interface for all music played by Ocarina.
