Fix 2732: Extract the full page geometry in lilypond-book

So far, lilypond-book tried to extract the line-width from the latex  
settings,
but not the full page geometry (height, width, margins). Instead, it simply  
used
the extracted line-with with the default paper size.

If the latex paper size is larger than the lilypond default paper size,  
then the
line-width will be larger than the page. Lilypond detects this and ignores  
the
wrong line-width.

The proper solution is to extract the full page geometry from the latex  
document
and use that for the lilypond snippet, too (unless an explicit papersize or
line-width was given, of course...)

As a side-effect, we now have some more snippet options:
-) paper-width
-) left-margin

-) paper-height
-) top-margin
-) bottom-margin

The latter options only have an effect on vertical stretching of  
multi-staff groups.

This patch also fixes a small mis-calculation of the text-width for  
multi-column
texts (the columnsep was subtracted only once rather than once per  
separation...)
