Purpose
=======
Add the properties fields in the search bar and allow to search
properties fields values.
Technical
=========
If the "active_id" is in the context, show only the properties
of the given definition record. Otherwise, show all properties
of all definition records.
Because fetching the properties definitions cost a SQL query and a RPC
call, the properties definition are fetched only if we unfold the
properties field (so it has no performance impact until we ask
explicitly to search a property).
