[skeleton] Don't use system site packages in tox environment As we changed this in cubicweb, there is a consensus that this is not the best practice so let us change it as well for skeleton.

[doc] Update "settings" pyramid documentation Document that without "bwcompat" we can use a development.ini file directly and add a dedicated section to list configuration options.

[doc] Update the "quickstart" page of pyramid documentation Again mentioning the two modes of operations and dropping references to prior implementation.

[doc] Rewrite "pyramid" index page in the book We drop references to pyramid-cubicweb and cubicweb-pyramid, remaining of the merge in 3.24. We now mention the two possible operation modes (with bwcompat being true or false).

[doc] Drop documentation for cubicweb.pyramid.tools module Which, as documented, mostly consists of internals.

[doc] Drop reference to "make_cubicweb_application" in pyramid doc This function got renamed into config_from_cwconfig and this is arguably an internal detail so should not appear in the API documentation.

[doc] Remove trailing whitespaces in doc/book/pyramid/index.rst

[tox] Install "pyramid" dependencies in "doc" environment Otherwise most of the cubicweb.pyramid API doc fails to build. For this we skip installation in the "doc" environment and source the new requirements/doc.txt which will install cubicweb[pyramid], thus pulling cubicweb plus pyramid's dependencies. Furthermore this requirements/doc.txt would be useful to build to documentation on readthedocs.

[web/views] fix bad html in deleteconf with show_composite=True On an entity with no composite an additional item "None" was displayed.

[web/views] display unique composite entities in deleteconf When the entity has two relations to the same composite, display it only once.
