[PATCH] Lilypond-book: get rid of lilyquote snippet option, use quote instead

[Reinhold Kainhofer]

Here's a patch that removes the lilyquote snippet option, since it doesn't 
really give any benefit over using the quote option. The only difference 
between the lilyquote and quote options so far was that with lilyquote the 
texinfo and doctitle was outside the example block. 

However, we didn't use quote together with those texinfo texts, so there is 
really no need to have both. This patch changes the 'quote' snippet option to 
have the texinfo texts outside the @example section. So, all LSR snippets in 
our docs can now also simply use quote instead of lilyquote (I have a long 
patch for the docs that replaces all lilyquote with quote and removed 
lilyquote from the lilypond-book usage docs. I didn't include that patch here, 
because it touches so many files in Documentation/ and is a simple 
search&replace exercise that I will push once this patch is agreed upon).
