Merge Prime genre into Nursery Rhymes (15 songs combined)

Browse Source 
Moved 6 Prime songs (Twinkle Twinkle, Mary Had a Little Lamb, Happy
Birthday, Chopsticks, Lavender's Blue, Shortnin' Bread) into the
Nursery Rhymes genre using the rhyme() helper. Dropped Baa Baa Black
Sheep since it's the same melody as Twinkle Twinkle. Updated README
to reflect 18 genres, 124 synth pieces.
