CRM-19674 Add ability to see at a glance if a contribution is part of a recurring series

Note this is a subset of https://github.com/civicrm/civicrm-core/pull/9421/commits/c6ba3ef7253b4b27ac69f70d71b6a78d3475b635

It re-instates the display of the word recurring, but leaves out the extra column
for recurring & sortability based on that. This is mostly because I wanted to get the
PR resolved & merged & hence left out the stuff that did not
seem like I had a consensus on. However, I do think the loss
of sortability on recurring is a shame & hence kept a link to the
commit if anyone wants to revisit
