Missing libgs warning (latex2svg.py) and generation failing.

Problem was the the name looked for 'libgs' on linux platform it should
be 'gs'. On Ubuntu 16.04 find_library gives 'libgs.so.9'

Last, but not least, LaTeX packages... (not small ones indeed!)

```
sudo apt-get install texlive-base
sudo apt-get install texlive-latex-extra
sudo apt-get install texlive-fonts-extra
```
