Adding songtemplate file

@andrewmaxin 

This is all I would really like to see. I don't really need to have two-column layout, and I'm not sure how that would work with the lines of the song and the `nbsp`s and such.

I've added the `.SongPart` CSS, as well as a div that wraps each part of the song in that class. It works how I expected, making sure that there aren't any orphans across printed pages!
