Title: [imp #94] Add new system compilers

Adding common \LaTeX compilers makes it possible to compiler more
documents.
So, by default we now have:
- pdflatex (default compiler)
- latex + dvipdfm,
- xelatex,
- lualatex

\BlueLaTeX assumes that these tools are installed on the system and
does not check for their existence.

If problems arise on some platforms, we should have a look at how to
make it detect if these tools are present in a portable way (well,
problem is probably on windows, which has no `which` command, and I am
not aware of any similar command, help is welcome here).

This commit closes #94
