I integrated more feedback from Rauno into the Contributor's Guide.

Ticket #1262 is still causing trouble. Rauno stumbled over it, Travis stumbles over it… now it seems that I finally got it: The real problem is that bleach requires version <0.99999999 of html5lib while weasyprint requires version >=0.999999999 of that same library. So you cannot currently use both bleach and weasyprint. The good solution for this is to update bleach so that it works with the newes version of html5lib.

Workaround for now: remove all version requirements, and make lino.mixins.bleached again less strict: don’t raise an exception, just log a warning when bleach is not installed. This is as it was until last week. The problem with this workaround is that it might be a time bomb because bleach is currently inactive and might become active at some unexpected moment in the future.
