[pkg] Prepare 3.20.8

[js] simplify cw.log implementation There's no need to rebuild and array and join its content, just call console.log with ``arguments``. The only trick is that console.log must be called on a console instance.

[web/views] don't force http redirect on logout We no longer forbid anonymous browsing on https, so we can keep the same scheme when logged out. Closes #5507479.

[views/schema] extract a hardcoded css class attribute

[formwidgets] move TextArea constants to the class level This will make it easy to override them.

[server/test] fix broken test The first bad revision is: changeset: 10396:82071f767cb8 user: Sylvain Thénault <sylvain.thenault@logilab.fr> date: Thu Jun 11 17:35:11 2015 +0200 summary: [schemas] cwuri should be read-only This changed the number of RQLExpressions to be more than the number of CWRelations in the test's schema. Related to #5457566.

[test] typo in entities test comment

[cwconfig] typo in comment

[serverctl] allow changing the log level for source-sync command When calling this from cron we only want to see output if something fails.

[web, urlrewrite] remove unused `cachekey` argument from `rgx_action` (closes #5355967) this argument prevent from generating the resulting rset descripition

[web] Fix the path to the `static directory` (closes #5355965)

[web/json] Controller.publish must return encoded data We were mixing binary from super() and text from our params, thus wrongly returning text. Closes #5507573.
