Merging Patch Release 2016-06-15 back to master

This line can safely be removed since it does not impact
styling (nothing is being supplied to calculate).

Reference [here](http://www.w3schools.com/cssref/func_calc.asp)

This was a typo that was missed, and is not resulting in any styling.

Removing it is a no-op.

The original committer does not work in this code anymore, and
it is old enough such that changing it would be more disruptive.

A more considerate outer_atomic.

A named outer is suitable when dealing with IntegrityErrors. It only
checks that it is not nested under an atomic only if it is nested
under enable_outer_atomic(name=<name>). This way only the view which
is causing IntegrityErrors needs to have its automatic transaction
management disabled and other callers are not effected.

Changed refund log level to warning.
