Reverted former redundant patch, got confused by legacy web modules
been translated with earlier versions. They had a different directory
structure and registered erraneous domain directories.
This patch fixes the list, does an additional safety check (dirname must
end with .UTF-8) and strips .UTF-8 from the locale name. Former regex
matched always and therefore blacklisted every translation.
List was showing useless stuff such as LC_MESSAGES and no language
but the default one. We should have a look whether LC_MESSAGES is
really needed, it looks so ugly.
One can now use $this->translate(msg) in a view or controller without the
need to pass the module domain (web&cli). Forms still need to be built
with _t(msg) and _mt(dom, msg).
