[pkg] 3.19.10

[i18n] Update translations Related to #5012581.

[config] Lowercase the FQDN we get from the OS (closes #5040345) Browsers convert the host name part of URLs to lowercase. This has the unfortunate effect of triggering various CORS error messages in CubicWeb (because the Origin: header will contain lowercase letters). As per RFC 4343, host name comparison should be case-insensitive. So let's put it in lowercase when we grab it from the host system. If admins put uppercase letters in "host" or "base-url" in their all-in-one.conf, then it's their fault.

[web/views] Honor 'action' attribute on AutomaticEntityForm, closes #4943392 On AutomaticEntityForms, get_action used to bypass the logic from FieldsForm.form_action() which handles the 'action' attribute itself, preventing callers from overriding it at selection time. This capability is used by the inlinedit cube. In a nutshell, we let the deprecated AutomaticEntityForm.get_action() raise an AttributeError, which allows FieldsForm.form_action() to handle it properly.

[docstrings] fix project-wide English language mistake Even though 'u' is a wovel, it may be pronounced 'yu' which is a consonant sound. In such cases precede it with 'a' instead of 'an'.

[doc] Don't pretend we know cubicweb runs on mysql As far as I know it hasn't been tested in years.

[test/i18n] Update reference po file following 75cd7df5c32e This changeset added a (missing) message "add a <etype>", so reference po file needed an update.

[devtools] add a method on CubicWebTC to fake data posted by standard cw forms. Closes #4985805
