at: upgrade to 3.1.14 - seems to solve problem with kernel > 3.5

'atd' in release-14.04 doesn't work on my system, since executing scheduled programs kills the daemon (same behaviour as described in here: https://lkml.org/lkml/2012/10/12/388).

I upgraded the at package from 3.1.12 to the newest version I could find (3.1.14) and the problem seems to go away - 'at' now works like a charm. 

Kind regards,
