Add use of ID as implicit alias in wbsearchentity

This is not a good solution as wbsearchentities has some
serious issues, it is a simple quickfix for two things.
First it assures that the absolute matches are always
included in the set, unless the limit is set so narrow
as some of them are chop'ed off. Ssecond it assures that
if an item is named by its ID it will always be included.

The module should later on be rewritten to do the searches
as a single query, that is it should do a self-join and
sort the result set. It should also supply the ofset to
the query to make paging more efficient.
