Altered ContributionRecur page so that the list of contributions related to a
recurring contribution are shown when viewing said recurring contribution.

Implemented by running CRM_Contribute_Form_Search ebedded within the page and
including CRM/Contribute/Form/Selector.tpl template within the page's
template. Also included ContributionTotals.tpl to show, which I though could
be cool.

CRM_Contribute_Form_Search class is very hard to read and maintain, which is
why it was found better to look for related contributions manually and show
them using an ajax datatable.

Added new Page that shows related payments for a given relted contribution in
a data table and included the table on recurring contribution's detail view
using an ajax call.
