Subject: [PATCH] Make "column"-property of Errors enumerable

Fixes #1284

Appearently, there is a use-case of stringifying the error in order to
evaluated its properties on another system. There was a regression
from 4.0.5  to 4.0.6 that the column-property of compilation errors
was not  enumerable anymore in 4.0.6 (due to  commit 20c965c) and
thus was not included in the output of "JSON.stringify".
