Merge branch 'master' into sphinx-migration
First pass from converting `aura2-design.tex` to rst directly without using
wiki:
    - generated with `pandoc -f latex j-t rst -RS --normalize --toc
                      --reference-links -o design.rst`
    - Fixed inconsistent headers
    - Anything that couldn't be converted was kept as raw LaTex for this pass.
Second pass:
- got rid of `\colorbox` declarations, as rst roles fulfill this purpose.
- converted command invokation examples accordingly
Third pass:
- set haskell as default highlighting language
- made role use consistent by matching roles to colors in the original tex file
Fourth Pass: Made a couple of nestd/literal lists definition lists
Fifth pass: converted last bits of raw latex.
Updated localisation guide to reflect changes made in `src/Aura/Languages.hs`
Removed tex file, as conversion is complete.
Multilingual PDF generation works now. Requires xelatex and WenQuanYi Micro Hei
font.
Hand-tuned the guides to make them more consistent with the edits I made in the
design doc.
Update localisation.rst

fixed typo - "bt p" instead of "p".

Moved most documentation to doc directory, managed by sphinx

- All of what was previously `.md` or `.tex` is now `.rst`, and can be compiled
  to html or pdf by running `make html` or `make pdf` provided you have sphinx
  and xelatex (available in `texlive-bin`) installed.
