Update template for ancient music transcription

[Stefan Slapeta]

Hi,

I'm quite new to lilypond and it took me some hours to find out why 
lyrics don't work as expected when using the template for ancient music 
transcription (D.5.1).

Referring to some newsgroup posts (http://tinyurl.com/2z6jlr, 
http://tinyurl.com/28yyhw), I propose to update this template to save 
others from investing the same amount of time again.

1)
Take the "bassusLyrics" out from the StaffGroup.

2)
Insert this sequence in the layout section:

   \context { \Lyrics \consists "Bar_engraver" }

   \context { \StaffGroup \consists "Separating_line_group_engraver" }

   \context { \Lyrics \override BarLine #'transparent = ##t }


Thanks in advance!

BTW, I'm still struggling with other ancient music issues ...
