LaTeX improvements

[rodarima]

Hi,

The GASPI specification provided in http://www.gaspi.de/, currently:

https://raw.githubusercontent.com/GASPI-Forum/GASPI-Forum.github.io/master/standards/GASPI-17.1.pdf

has two major typesetting issues:

1. The document is using non-vectorial fonts, which are very ugly for use in computer screen. Here is what I see in okular (same in zathura and mupdf):
   
   While, if I compile the document from the repository using pdflatex GASPI_Standard_Draft.tex it shows ok: I'm not sure what causes the difference. This is what I found on the PDF metadata; maybe is related to the pdfTeX version:

# The original from the GASPI-forum website
% pdfinfo GASPI-17.1.pdf | egrep '(Creator:|Producer:)'  
Creator:         TeX
Producer:        pdfTeX-1.40.16
# The one I compiled:
% pdfinfo GASPI_Standard_Draft.pdf  | egrep '(Creator:|Producer:)'  
Creator:         LaTeX with hyperref
Producer:        pdfTeX-1.40.20

2. The PDF document doesn't have a PDF index enabled, which I find very useful to quickly jump between sections, specially when I'm not familiar with the complete structure of the document. I was able to enable the index with the hyperref package, but there is a conflict with one of the macros that cause the document to fail. I disabled the macro, as I don't know how to fix it. Here is the patch:

After enabling the index generation, I can see the sections and quickly jump between them:
