Spotted by chance. Seems unlikely to be hit, but that would be a stupid
arbitrary limitation nevertheless.

ComplexQuery bypasses SearchKey mechanism and makes assumptions
SQLCatalog.{search|count}Results does not do.
Instead, reserve a name, and complain if it is passed by caller.

"query" argument is not supposed to be different from any other
argument (argument name is [pseudo-]column name, unknown coluns are
rejected, and "None" means "IS NULL" SQL comparison), but is accidentally
special-cased in ERP5Catalog. This special-casing is to be removed, so
update all callers relying on this glitch.
Also, avoid using Query.

Also, do not use deprecated parameter name to pass a logical operator.

ERP5Storage.putAttachment is going to return a blob instead of a
string in the resulting event.target.response. This patch allows
to handle blob responses and keep backward compatibility.
