Bug 17698: (follow-up) Changing to Koha Objects style, adding circ sidebar

Marcel, can you please have a look at this patch. I tried to implement
the change
my @notes = $schema->resultset('Issue')->search({ 'me.note' => { '!=', undef } }, { prefetch => [ 'borrower', { item => 'biblionumber' } ] });
to
my @notes = Koha::Checkouts->search({ 'me.note' => { '!=', undef } }, { prefetch => [ 'borrower', { item => 'biblionumber' } ] });
but am having problems on the template side. I can access the item and
biblio information about the issue, but not the borrower information,
even though the query is definitely pulling it correctly. Any
suggestions or ideas as to why this breaks?

This patch also adds the implementation of the circSidebar.
