added a way to add custom escaping strategies

This adds the possibility to define custom escapers that can be used with the `escape` filter.

That would close #1178 and #1177, but I'm not sure that this is a good idea.

What do you think?

minor#1206 Refactored the installation docs (fabpot)

Refactored the installation docs

The idea is to get back a simple and straight to the point into chapter. As Composer is now the defacto standard to install PHP deps, I've moved everything related to the other installation methods in a new chapter.
