stable/2.14 and fixed_2_x_y

[Graham Percival]

stable/2.14 has been branched.  Carl is the only person who should
touch that branch, other than me making release announcements and
updating the version number.  All future 2.13.x releases will be
made from stable/2.14.

If you fix something in the issue tracker, mark it fixed_2_15_0.
Carl will add fixed_2_13_61, _62, _63, _64, etc., when he
cherry-picks the patch to stable/2.14.

Cheers,
- Graham
