New songs added and songbooks updated.

Hello Wuggers,

I’ve uploaded some new songs which have also been included in the WUG songbook. They are: Deep In The Heart of Texas, Singing In The Rain, Things, Will You Still Love Me Tomorrow and the WUG Intro version of You Are My Sunshine. I’ve also added When The Saints Go Marching In to the finger-picking songbook, so lots to practice!
