[WIP v3 0/5] Update Sphinx to 1.4.8

[Danny Milosavljevic]

This patchset updates Sphinx to 1.4.8. It has been tested unsuccessfully on 
branch "master" using:

$ guix build `guix refresh -l python-sphinx python2-sphinx`

It fails in python-matplotlib due to latex complaining at "\footnote[*]" in 
Matplotlib.tex:171. If I manually change it to "\footnote[1]" it works. The 
file Matplotlib.tex is generated by Sphinx.

Should "\footnote[*]" work in LaTeX? If not, how does it end up there?

Danny Milosavljevic (5):
  gnu: Add python-snowballstemmer.
  gnu: Add python-sphinx-cloud-sptheme.
  gnu: Add python-sphinx-alabaster-theme.
  gnu: Add python-imagesize.
  gnu: Update Sphinx to 1.4.9
