Configfiles and latex

### Split configfiles out of TeX document.
This gives us the possibilty to give complete, downloadable
examles; All config files are linked to a modifieable URL,
the default being https://bettercrypto.org/static/configuration/...
(the `rsync` step is updated accordingly)

Next step: replace ciphersuite automatically in those config files?

Most configfiles are based on their Debian Wheezy, sometime Jessie,
defaults.


### Nicer tables 
More compact, with alternating row colors for readability.

### Use SourceCode Pro additionally to OpenSans
On that way, get rid of requiring people to install the fonts manually.
Instead, put them in a `texmf` tree and use it when running LaTeX. This
is already automated in the `Makefile`.
