4.7 port: restore 'edit row' functionality

whoops, just found this issue, after i had already submitted http://drupal.org/node/68276. not much here yet, and the CHANGELOG already refers to #68276, so i'm marking this as the duplicate.

bah, so much for "cleaning up the issue queue". :) i should have read through the whole queue more closely. there's yet another older issue that my new ones were duplicate with. so, i'm going to do what's right, and open the oldest issues and mark the newer ones as the duplicates...

while i was at it, i ported the delete row stuff to 4.7.x FAPI, too, and fixed the broken "Cancel" link there.

the 5 minute review says it looks good and works as advertised.

The only comment I had was that the "edit" and "delete" action links might be better placed at the far left of the table instead of the far right, but I realized that this would make it inconsistent with the table view page. On many tables, though, the action links are off the page in any browser size that I can open.

thanks for the review/testing. and, perhaps moving the links would be a good move. however, that's a UI feature request. i was just trying to replicate the 4.6 functionality/UI as closely as possible. ;)

Looks good, please merge.

committed to HEAD as revision 1.44.

and now, time to make the branch and release nodes so we can finally close http://drupal.org/node/59073. ;)
