Bug 24356: Make objects.search prefetch embedded relations
This patch makes the Koha::Object(s) derived classes expose information
about prefetch-able relations. This is then used by a new helper to
generate the prefetch information for the DBIC query.
To test:
1. Apply this patch
2. Run:
$ kshell
k$ prove t/db_dependent/Koha/Object* \
t/db_dependent/Koha/REST/Plugin/Objects.t \
t/Koha/REST/Plugin/Query.t
=> SUCCESS: Tests pass!
3. Sign off :-D
