LaTeX: remove \setlength\columnsep{-1cm}

The idea of this was to get the chapter titles to be on a single line in
the two column format provided by multicol. However, it occasionally
caused the columns to overlap and it wreaked havoc with the auto
generated index in the book version.
Adjoint continuous functors of sites

Hopefully this makes the discussion of adjoint functors a bit clearer
here and there.
Augmentations give morphisms of topoi
Small clarifications
Cohomology of simplicial spaces
Improve chapter on hypercoverings

Made it more general so it works also for the hypercoverings exactly as
defined in Verdier's original.
Remove math mode from section titles

This wasn't displaying right on the website and it is probably a bad
idea typographically anyway. Thanks to Jeroen Zuiddam for pointing out
the issue.

New condition on cocontinuous functors

In this commit we introduce an additional property a cocontinuous
functor u : C ---> D between sites could have. The property is roughly
that one can ``pull back'' coverings to coverings along u. This
property is often satisfied in practice (for example localization
functors always satisfy it) and had so far escaped our attention. It is
useful in the setting of simplicial sites defined using cocontinuous
functors (see next commit).

Of course, we really need to work on the whole chapter extensively.
