[rrd-developers] [patch] generate 'legal' SVG/XML code

the code  has 2 problems.

1. it was not printing the right xml and would lead to
" y="98.17 font-family="<value of RRD_DEFAULT_FONT>""

I don't think this is correct, as it should be putting in the font 
family name, not the path/filename of the TTF file.

this patch fixes up the format of the string to make it default xml.
it also shoves 'Helvetica' (it should put svg_default_font in I guess).

so the only problem I still have is the ':' in the comment/gprint fields 
  screwing up the parsing.. any takers.. ???
