Some views were trying to make fields invisible thanks to
`attrs="{'invisible': 1}"`.
This is not supposed to be valid as an attrs value is supposed to be
a domain and not a number. To make the fields always invisible, use
the "invisible" *attribute*. This also allows the client to make the
fields invisible without any domain computation.
However, to keep supporting those kind of attrs and to be more generic,
the Domain class is adapted by this commit to consider numeric domains
to be valid (numbers different than 0 are considered "true" domains and
0 is considered a "false" domain).
