DomainTool: Unite inner-join and left-join predicate lookups 

Improvement: As proposed by Jean-Paul when this extension was added (2010),
allows mixing left- and inner-join lookups.
Improvement: Now it is not required to specify tested_base_category_list
to enable inner joins: they will automatically be used whenever a base
category set on context matches the preference. If all categories set on
context match the preference, then no left join will be used at all.
